RHCLOUD-50315: Apply workflow remediations

[tylercreller]

• Applies fixes for workflow weaknesses as suggested by Glasswing
  • Pins workflows
  • Moves workflow permissions under children to be more specific
• Group dependabot PRs

Summary by CodeRabbit

• Chores
  • CI, deployment, and link-check workflows now use fixed action versions for more consistent execution.
  • Workflow permissions are scoped to the specific jobs that require them.
  • Link-check failures now trigger issue notifications only when the scheduled check fails, including step-level failures.
  • Existing build, deployment, and link-check triggers remain unchanged.
  • Deployment and automated link validation continue to run with improved workflow safeguards.

📝 Walkthrough

Walkthrough

The workflows pin third-party actions to commit SHAs and scope permissions to jobs. Checkout disables persisted credentials where updated. Scheduled link-check failures can create issues. Dependabot groups npm and GitHub Actions updates.

Changes

Workflow hardening and link-check notification

Layer / File(s)	Summary
Scoped permissions and pinned actions .github/workflows/ci.yml, .github/workflows/deploy.yml, .github/workflows/link-check.yml	The workflows use pinned action commits. Permissions move to the jobs that need them. Updated checkout steps disable persisted credentials.
Scheduled failure notification .github/workflows/link-check.yml	A separate notification job runs when a scheduled link check fails. It receives issues: write permission and invokes GitHub Script.

Dependabot update grouping

Layer / File(s)	Summary
Dependency update groups .github/dependabot.yml	Dependabot groups npm updates under npm-dependencies and GitHub Actions updates under github-actions.

The link-check job retains its GitHub token for later commands, increasing exposure if a later action is compromised. The fix is small and localized.

🟡 Minor · Disable credential persistence for this checkout. · link-check.yml:21-26

.github/workflows/link-check.yml:21-26
🔒 Security & Privacy | 🟡 Minor | ⚡ Quick win

Disable credential persistence for this checkout. actions/checkout@v7 defaults persist-credentials to true. It persists the token-backed Git credential for subsequent steps. The lycheeverse/lychee-action step already receives GITHUB_TOKEN through its token input, and notify is a separate job. No step requires persisted Git credentials. A later or compromised action could otherwise run authenticated Git commands with this token.
