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

Conflicts:
- `.github/workflows/build-image.yml`:
  Upstream updated `docker/build-push-action`, and we a different config
  for `docker/metadata-action` so the lines directly above were different,
  but it's not a real conflict.
  Upgraded `docker/build-push-action` as upstream did.
- `app/javascript/mastodon/features/compose/components/compose_form.js`:
  Upstream changed the codestyle near a line we had modified to accommodate
  configurable character count.
  Kept our change.
