Conflicts:
- `.prettierignore`:
Upstream removed it, replaced by `.oxfmtrc.json`.
We had glitch-specific files in there.
Updated `.oxfmtrc.json` accordingly and removed `.prettierignore`.
- `config/formatjs-formatter.js`:
Upstream switched to `oxfmt` from `prettier`, and some rules are slightly different.
Glitch-soc had extra code in there.
Reformatted appropriately.
- `eslint.config.mjs`:
Upstream moved some configuration from `eslint.config.mjs` to `.oxfmtrc.json` where
glitch-soc had slightly different configuration.
Removed it from `eslint.config.mjs` as well and updated `.oxfmtrc.json` accordingly.
- `package.json`:
Upstream changed script definitions textually adjacent to one that we have modified.
Applied upstream's change, keeping the textually adjacent modified script intact.
