## Summary
- Add `UK1` and `US2-FED` to the Datadog region dropdown in the log
drains studio UI
- Add the same two regions to the Datadog region list in the log-drains
docs page
The Logflare backend added support for these two Datadog regions in
[Logflare/logflare#3790](https://github.com/Logflare/logflare/pull/3790)
(shipped in v1.50.1), but the studio dropdown and docs were never
updated, so customers on UK1 or US2-FED couldn't actually select their
region when setting up a Datadog log drain.
## Test plan
- [ ] Open Project Settings → Log Drains → add a Datadog destination and
confirm UK1 and US2-FED appear in the Region dropdown
- [ ] Confirm a log drain configured with `UK1`/`US2-FED` saves and
sends events successfully
