No "Approve and run" button on this PR: elias-pap/youtube-share-clip#60

According to step 5 from this section of the docs: https://docs.github.com/en/actions/managing-workflow-runs/approving-workflow-runs-from-public-forks#approving-workflow-runs-on-a-pull-request-from-a-public-fork

"If you are comfortable with running workflows on the pull request branch, return to the Conversation tab, and under "Workflow(s) awaiting approval", click Approve and run."

There should be an "Approve and run" button on Conversation tab, but there isn't one.

Usage error. The workflow was set to be triggered on push event but this does not work for PRs from forks. Changed it to be triggered on pull_request event.
