Implementation notes from Kickoff:

• We will make the following changes directly to release_notes.yml, it can resolve the difference between a comment trigger and a workflow_dispatch trigger for sourcing the releasePR number.
• release_notes adds the following trigger: `on: {  issue_comment: {  types: [created] }}`

• When a comment triggers the workflow 
• Use ${{ github.event.comment.body == 'run release_notes' }} to check for the correct trigger string
• Use ${{ github.event.issue.number }} to get the release PR's number
• Use ${{ github.triggering_actor }} to get the current user ENSURE not empty string
• Use gh api \ "/repos/${{ github.repository_owner }}/${{ github.repository }}/collaborators?permission=admin" --paginate --jq ".[].login" \ | grep -q "$triggering_actor" to get the list of admins
• Using the gh CLI, we can hit the API endpoint for our repo, listing collaborators with the permission "admin"
• The paginate flag will fetch until we've gotten all results
• Use the jq flag to get just the username out of the JSON
• grep will exit 1 or 0 for finding a match or not
• Check the exit code with bash if/else

• When workflow dispatch triggers the workflow
• Use ternaries and if conditions on steps as needed to reuse the same workflow
• Skip admin checking, and ensure the releasePr is set correctly before running the action
