chore(ci): skip Link job on fork PRs (#4915)

The Link job requires SUPABASE_ACCESS_TOKEN and SUPABASE_PROJECT_ID secrets which are unavailable to fork PRs. Without this guard, the job always fails on external contributions, creating a misleading red CI status that distracts both contributors and reviewers. The if condition checks github.event.pull_request.head.repo.fork and skips the job entirely for fork PRs, showing it as 'skipped' instead of 'failed'. On pushes to develop and PRs from branches within the main repo, the job continues to run normally.
