chore: Set permissions for GitHub actions (#12462)

Motivation:

Restrict the GitHub token permissions only to the required ones; this way, even if the attackers will succeed in compromising your workflow, they won’t be able to do much.

Modifications:

- Included permissions for the action.

  https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#permissions
  https://docs.github.com/en/actions/using-jobs/assigning-permissions-to-jobs

Result:

Secure GitHub actions
