Conflicts:
- `.github/ISSUE_TEMPLATE/bug_report.md`:
Upstream added the `bug` label to bug reports.
Did the same.
- `app/services/fan_out_on_write_service.rb`:
Upstream put DMs back into timelines, glitch-soc was already doing it.
Ignored upstream changes.
We don't have releases, so it don't make sense to mention.
On the other hand, a lot of our code is from upstream, so encourage people to
check whether it is a bug in glitch-soc or upstream.
