Merge commit 'b922ad7a1b4bc8d968d0df2c7f307d4fec53435d' into glitch-soc/merge-upstream

Conflicts:
- `package.json`:
  Upstream changed various script definitions in lines surrounding the one for
  `i18n:extract`, which had glitch-soc-specific changes.
  Updated the scripts as upstream did, while keeping our changes to
  `i18n:extract`.
