Conflicts:
- `config/webpack/configuration.js`:
Upstream updated the `js-yaml` dependency, which changed how to call it.
Those changes conflicted because that code is pretty different in glitch-soc
which has to deal with its more complex theming system.
Proceeded to the same compatibility changes in glitch-soc's code.
- `package.json` and `yarn.lock`:
Not really a conflict, just glitch-soc-specific dependencies textually too
close to some dependencies updated upstream.
