🧰 Task

PR comment with docs build preview ala numpy:
numpy/numpy.org#596 (comment)
they use netlify: https://docs.netlify.com/site-deploys/notifications/#github-pull-request-comments

Looks like vercel also has something similar:
https://vercel.com/docs/concepts/deployments/comments/integrations

I'm not clear on the strengths and weaknesses of these, but it would be a super nice feature.
