update action to run on node22

[waheedahmed]

This pull request introduces configuration options for merge retry logic and updates the Node.js runtime version used by the GitHub Action. The main changes are:

Merge Retry Logic:

• Added merge-retries and merge-retry-sleep options to the configuration, allowing users to control how many times the action retries merging and the delay between retries. This provides more flexibility and robustness when handling transient merge failures.

Runtime Update:

• Updated the Node.js runtime version for the GitHub Action from node20 to node22, ensuring compatibility with the latest features and security updates.

The action runtime is being bumped to Node 22, but the repo CI workflow (.github/workflows/test.yml) still runs lint/tests on Node 20 only. To reduce the risk of Node-version-specific regressions, consider updating CI to run on Node 22 (or a matrix including both 20 and 22) so the tested runtime matches what users will run in production.

The README uses both "enqueuing" and "enqueueing" (e.g., the label/required-approvals rows use "enqueuing", but these new rows use "enqueueing"). Consider standardizing the spelling across the README for consistency (pick one form and use it everywhere).
