Add a docs feedback widget to allow upvoting and downvoting pages.
Votes (completely anonymized, barely more than a counter) go to a database in the main supabase-com project. If the user has accepted telemetry, the votes also go to Logflare with a bit more info. Post-vote, logged-in users can leave a comment, which goes to the `platform/feedback/send` endpoint. There is a warning in the feedback modal that the feedback is not anonymous.
**feat:** adds a component to display API endpoints and anon keys in docs if user is authenticated
makes the getting started UX smoother so users don't have to jump back and forth between docs and trying to find their keys in dashboard
**out of scope:** it would be very cool to display these directly in the code blocks. I looked into it and it would require quite a bit of work forking and modifying code-hike, so out of scope for now
