[Github] PRs missing build CI checks

[htcfreek]

Repository Branch

main

❌ Actual Behavior

The build ci checks aren't running anymore after updating PRs against current main. Why?

xref: #33703

✔️ Expected Behavior

Build CI checks are executed after pushing changes.

Unfortunately, we've had to switch to a security mode that requires a team member to comment on a PR before the CI will kick in. Sorry. You'll probably see this across all the Microsoft projects you contribute to in the coming weeks. 😦

Is this a temporary thing? What is the reason for this decision?

Wouldn't it make sense to block merge until ci succeds? (I have in mind that GitHub supports runs after approvals or something similar.)
