Update workflow to protextfrom but run external PRs (#2440)

🔧 (workflows): update GitHub Actions workflows for improved PR handling

Comment out the labeler workflow to temporarily disable it, possibly for
debugging or performance reasons. Modify the main workflow to use
`pull_request_target` instead of `pull_request` for better security and
add specific event types to trigger the workflow. Introduce conditional
logic to ensure the workflow only runs under safe conditions, such as
when a PR is labeled 'safe-to-build'. Add steps to remove the
'safe-to-build' label from PRs originating from forks, ensuring that
only trusted code is built. Update the checkout steps to handle both
push and pull request events correctly, ensuring the correct repository
and ref are checked out. These changes enhance the security and
flexibility of the CI/CD pipeline by ensuring that only safe and
intended code is built and deployed.
