Overview

Right now, .github/workflows/contributors.yml triggers https://github.com/JoshuaKGoldberg/all-contributors-auto-action to add a comment on contributions. Example: https://github.com/JoshuaKGoldberg/release-it-action/issues/14#issuecomment-1742738364

Although the comment's text indicates it's from a bot, it's still attributed to the username that posts it (in that comment's case, @JoshuaKGoldberg). Which I've always found odd. I think it'd make sense to instead seem to post from a more obviously bot-like name. Maybe, github-actions?

Additional Info

This might necessitate filing a feature request for a new input or two to https://github.com/JoshuaKGoldberg/all-contributors-auto-action. I haven't looked into it.
