Thank you so much for the contribution, @devanshkansagra.
I truly appreciate the time and effort you put into this PR, as it was a much-needed feature to allow maintainers to test changes visually before merging. Since I worked with you on this, I know how much time, effort, and research went into building and testing it on a dummy repo.

With all good intentions, I am merging it to see if everything works as expected.

Note: We understand the security risks associated with the pull_request_target and workflow_run triggers, and we have done our best to maintain a balance between convenience and security. However, if any security incidents arise due to this, we are ready to revert the changes at any time.

Thanks again, @devanshkansagra. Happy contributing!
