Fix: Add workflows permission to GitHub Actions

[adityamaru]

Problem

The release workflow failed with the error:

refusing to allow a GitHub App to create or update workflow 
`.github/workflows/buildkit.yml` without `workflows` permission

This happens when cherry-picking patches that modify workflow files.

Solution

Add workflows: write permission to both:

• release-patched-version.yml: Needed when cherry-picking patches that include workflow changes
• rebase-upstream.yml: Also needs this permission when rebasing includes workflow modifications

Testing

After this fix, the release workflow should be able to:

1. Cherry-pick patches that modify workflow files
2. Push branches containing workflow changes
3. Complete the release process successfully

---

Note

Grants workflows: write permission in release and rebase GitHub Actions to allow updates when workflow files change.

• CI/CD Permissions:
  • Add workflows: write to:
    • .github/workflows/release-patched-version.yml
    • .github/workflows/rebase-upstream.yml
