[lidel]

This PR

• stops deploying every main commit to inbrowser.link, and only does it on release publish event
• runs more strict smoke-tests in parallel for faster build
  • investigate why w3s.link CAR fails removed, unrelated issue with CF CDN
• includes git revision in produced dist/index.html for easier debugging
• creates PR with unreleased things (merging publishes them as new release and updates changelog)
  • generated temporary UCI_GITHUB_TOKEN, Expires on Thu, Jun 13 2024. (will switch to proper one after moving to ipfs/ org, as tracked in Rename and move to ipfs/ org #80 )
  • attach CAR to github release
• fleek image missing git

I've moved smoke tests to separate job, and made it run once an hour – will check on it on Monday.
Merging this, as low risk, and want to test release-please (works only from main).

So far things look good, release-please created #120
