chore: Update Android SDK from 5.11.0 to 5.11.1 (#7)

## Summary
Bumps the LaunchDarkly Android Client SDK dependency from `5.11.0` to
`5.11.1` (patch release).

## Review & Testing Checklist for Human
- [x] Verify CI build passes — this is an Android project and the build
was not tested locally
- [x] Confirm `5.11.1` is the latest published version of
`com.launchdarkly:launchdarkly-android-client-sdk` on Maven Central
- [ ] Build and run the example app on an emulator or device to confirm
it initializes the SDK and evaluates a flag successfully

### Notes
Single-line patch version bump. No API changes expected. No README
update needed since it does not reference the SDK version.
