Display HTML test report URLs in check run summaries

Resolves #252

Description

After extensive testing of GitHub Actions check run behavior, we've found that GitHub Actions consistently overrides any custom details URLs with its own workflow run URLs. This appears to be a platform-level behavior that cannot be bypassed. As a result, this PR implements an alternative approach that ensures the HTML test report URLs are prominently displayed in the check run summaries.

Changes:

• Added GitHub Checks marketplace action (LouisBrunner/[email protected]) for reliable check run creation
• Created separate check runs for test reports with clear naming
• Added HTML report URLs prominently in check run summaries
• Added proper error handling for missing HTML reports
• Added dummy workflow to demonstrate and test check run behavior

Key Findings:

• GitHub Actions automatically overrides check run details URLs with workflow run URLs
• This behavior is consistent across different approaches:
  • Direct GitHub API calls
  • GitHub Checks marketplace action
  • Post-job check run creation
  • Different conclusion statuses (success/failure/neutral)
• Solution: Display HTML report URLs in check run summaries for easy access

Testing

The changes can be tested by:

1. Running the dummy check result workflow to verify check run creation
2. Observing that the HTML report URL is clearly displayed in the check run summary
3. Running the connector tests workflow (after approval)
4. Verifying that test report check runs show proper status and HTML report links
5. Confirming proper error handling when report generation fails
