Setting for custom config file location

[Splines]

It'd be awesome if this extension could allow for a custom file location of the .vscode-test.mjs file by means of an extension-test-runner.configFile VSCode setting.

For example, I renamed the file to vscode-test.mjs (missing dot at the beginning) and placed it in a .config/ folder (see also config dir proposal here). Then this works perflectly fine under the package.json > scripts key:

"test": "vscode-test --config .config/vscode-test.mjs"

However, this extension doesn't detect the file, so nothing works. A workaround is to still use the usual location, which is the workspace root directory.
