Copilot code review action failing with HTTP 403 insufficient permissions for artifact cleanup

[Manar-Elhabbal7]

Describe the bug/problem

The Copilot code review GitHub Actions workflow is failing consistently across multiple pull requests with an HTTP 403 permission error during artifact cleanup. The workflow exits with exit code 1 despite completing the review process.

Steps to Reproduce the bug/problem

1. Open any recent pull request in the foss42/apidash repository
2. Navigate to the "Actions" tab
3. Locate the "Copilot code review" workflow run
4. Click on the workflow run to view details
5. Scroll to the bottom of the job logs
6. Observe the error: gh: Resource not accessible by integration (HTTP 403)

Expected behavior

The Copilot code review workflow should complete successfully without HTTP 403 permission errors. The job should exit with code 0 (success) after completing the code review and cleaning up artifacts.

Proposed Solution

Add explicit permissions to the workflow configuration:

permissions:
  actions: write
  contents: read
  pull-requests: write

Or alternatively, disable artifact cleanup if not needed.
