Krzysztof CzuszynskiandCopybara-Service 8dd5a79b29 fix: Fix transcript finish
Merge https://github.com/google/adk-python/pull/3324

**Problem:**
ADK seems to not pass output/input transcription `finished` flag from the Gemini.

**Solution:**
Relaxation of checking conditions of valid llm_response for input/output transcription.

### Testing Plan

Unit test `test_receive_transcript_finished` checks if input/output transcription message with no text but `finished` flag is received.

**Unit Tests:**

- [x] I have added or updated unit tests for my change.
- [x] All unit tests pass locally.

**Manual End-to-End (E2E) Tests:**

Configure Gemini Agent to produce input & output transcriptions. Observe incoming transcript messages - to see if the finished flag appears at the end agents & users statement.
