Fix workflow documentation to use dynamic workspace paths (#879)

The Language Support Tester workflow documentation hardcoded
`/workspace/` paths, preventing the agent from locating test samples at
runtime. GitHub Actions workspace paths vary by environment (e.g.,
`/home/runner/work/{repo}/{repo}`).

## Changes

- **Updated path references in
`.github/agentics/language-support-tester.md`**:
  - Changed hardcoded `/workspace/` paths to `{workspace}` placeholder
- Added instructions to use workspace path from `github-context` section
  - Applied to JavaScript/TypeScript test samples path
  - Applied to Python test samples path
  - Updated "Important Notes" section references

The agent now receives the actual runtime workspace path via
`__GH_AW_GITHUB_WORKSPACE__` in the github-context and can correctly
construct paths to test samples:

```markdown
- Use the test samples at `{workspace}/test/serena-mcp-tests/samples/js_project/` (use the workspace path from github-context)
```

## Notes

Test sample files already exist in the repository with expected content
(`Calculator` class, `add` method, `format_number` function,
`package.json`). No code changes required.

> <issue_title>[language-support] Missing test samples for
TypeScript/JavaScript and Python language support testing</issue_title>
> <issue_description>## Summary
> 
> The Language Support Tester workflow references test sample
directories that do not exist in the repository, preventing proper
testing of TypeScript/JavaScript and Python language support with the
Serena MCP server.
> 
> ## Missing Directories
> 
> The following test sample directories referenced in
`.github/agentics/language-support-tester.md` are missing:
> 
> - `/workspace/test/serena-mcp-tests/samples/js_project/`
> - `/workspace/test/serena-mcp-tests/samples/python_project/`
> 
> ## Impact
> 
> - **Go language support**: ✅ Successfully tested with existing Go
files
> - **TypeScript/JavaScript support**: ❌ Cannot test - no test samples
exist
> - **Python support**: ❌ Cannot test - no test samples exist
> 
> ## Test Results
> 
> ### Go Language Support (✅ Working)
> 
> Successfully tested Go language support using the main repository
code:
> - `get_symbols_overview` on `main.go` returned functions: `main`,
`buildVersionString`, and constant `shortHashLength`
> - `find_symbol` successfully found the `main` function with correct
location and signature
> - `find_symbol` successfully found the `Version` variable in
`version.go` with complete info including documentation
> 
> ### TypeScript/JavaScript Support (⚠️ Unable to Test)
> 
> The referenced test directory
`/workspace/test/serena-mcp-tests/samples/js_project/` does not exist.
The repository contains no JavaScript or TypeScript files for testing.
> 
> ### Python Support (⚠️ Unable to Test)
> 
> The referenced test directory
`/workspace/test/serena-mcp-tests/samples/python_project/` does not
exist. The repository contains no Python files for testing.
> 
> ## Reproduction Steps
> 
> 1. Run the Language Support Tester workflow
> 2. Agent attempts to locate test samples at the documented paths
> 3. Paths do not exist in the repository
> 
> ## Recommended Solution
> 
> Create the missing test sample directories with appropriate test
files:
> 
> 1. Create `/workspace/test/serena-mcp-tests/samples/js_project/` with:
>    - `index.js` or `index.ts` with sample functions/classes
>    - `package.json` with project metadata
> 
> 2. Create `/workspace/test/serena-mcp-tests/samples/python_project/`
with:
>    - `calculator.py` with a `Calculator` class and `add` method
>    - `utils.py` with utility functions like `format_number`
> 
> Alternatively, update the testing workflow documentation to reference
existing test files or clarify that only Go language support needs
testing.
> 
> ## Additional Context
> 
> - Serena MCP server version: `ghcr.io/github/serena-mcp-server:latest`
> - Workflow: `.github/workflows/language-support-tester.lock.yml`
> - Task specification: `.github/agentics/language-support-tester.md`
> - Active project: `gh-aw-mcpg` (Go language configured)

 ## Important Notes
 
 - This workflow tests the Serena MCP server container specified in the repository configuration
-- The Go project is the main repository code in `/workspace`
-- TypeScript/JavaScript test samples are located at `/workspace/test/serena-mcp-tests/samples/js_project/`
-- Python test samples are located at `/workspace/test/serena-mcp-tests/samples/python_project/`
+- The Go project is the main repository code in the workspace directory (see workspace path in github-context)
+- TypeScript/JavaScript test samples are located at `{workspace}/test/serena-mcp-tests/samples/js_project/` (use the workspace path from github-context)
+- Python test samples are located at `{workspace}/test/serena-mcp-tests/samples/python_project/` (use the workspace path from github-context)
 - Issues created will automatically expire after 7 days if not addressed
 - Focus on testing actual language server functionality, not just basic container operations
 - Serena uses "typescript" as the language identifier for both JavaScript and TypeScript files
