chore: AI flag cleanup action trigger workflows (#10288)

https://linear.app/unleash/issue/2-3671/adapt-ai-flag-cleanup-action-to-use-our-unleash-bot-gh-app

Adapts our AI flag cleanup action to use our Unleash-Bot GH app. The
main side-effect we're interested in is that this now automatically
triggers the PR checks.

Example PR: https://github.com/Unleash/unleash/pull/10287
