ci: Trigger requirement-pass on merge_group

[daquinteroflex]

Greptile Summary

This PR adds merge_group to the conditional trigger for the pr-requirements-pass job in the GitHub Actions workflow. The change ensures that the requirements validation job runs consistently when GitHub's merge queue feature is used.

The modification aligns the pr-requirements-pass job with the existing determine-test-scope job, which already handles merge_group events (lines 96-99) by setting both local_tests and remote_tests to true. Without this change, there was an inconsistency where merge queue events would trigger the test determination logic but skip the final validation step.

This is a CI/CD configuration fix that ensures proper test validation across all supported GitHub event types: pull_request, pull_request_review, and now merge_group. The change maintains the same rigorous testing standards for merge queue operations as for manual merges.

Confidence score: 5/5

• This is a safe CI configuration fix that adds missing event handling without changing existing logic
• The change follows the established pattern already present in the workflow file and fixes a clear gap in event handling
• No files need additional attention - this is a straightforward one-line addition to align job triggers
