Merge branch 'main' into glitch-soc/merge-upstream

Conflicts:
- `README.md`:
  We have completely different contents. Kept our version.
- `package.json`:
  Not a real conflict, just an upstream dependency udpated
  textually too close to a glitch-soc-only dependency.
  Updated dependencies like upstream.
- `streaming/index.js`:
  Conflict due to code style changes on parts that were
  modified in glitch-soc to handle local-only toots.
  Changed style according to upstream.
