refactor(make-gitignore.py): remove requests dependency, use urllib

[Copilot]

Remove third-party requests dependency to make the script work on any Python installation without requiring pip install.

Changes

• Replace requests.get() with urllib.request.urlopen()
• Add exception handling for urllib.error.HTTPError (HTTP status codes) and urllib.error.URLError (network failures)

# Before
resp = requests.get(self.raw_url())
if resp.status_code != 200:
    if resp.status_code == 404:
        raise ValueError(f'No gitignore template regarding "{self.lang}"...')
    raise ValueError(f"{resp.status_code=}")
return resp.content.decode('utf-8')

# After
try:
    with urllib.request.urlopen(self.raw_url()) as resp:
        return resp.read().decode('utf-8')
except urllib.error.HTTPError as e:
    if e.code == 404:
        raise ValueError(f'No gitignore template regarding "{self.lang}"...')
    raise ValueError(f"HTTP Error {e.code}: {e.reason}")
except urllib.error.URLError as e:
    raise ValueError(f"Network error: {e.reason}")

All existing functionality preserved including error messages for 404s and other HTTP errors.

Yes, the PR is ready to merge. The refactoring is complete and tested:

✅ Removed requests dependency, now uses built-in urllib
✅ All functionality preserved and working (tested with --python, --go, --favorite, --default-envs)
✅ Error handling for both HTTP errors (404) and network issues
✅ Code review passed
✅ Security scan (CodeQL) found no vulnerabilities

The script now works on any Python installation without requiring pip install.
