refactor: Move google-adk instrumentation to instrumentation-loongsuite

- Rename from opentelemetry-instrumentation-google-adk to loongsuite-instrumentation-google-adk
- Move from instrumentation-genai/ to instrumentation-loongsuite/
- Update pyproject.toml with loongsuite naming conventions
  - Change package name to loongsuite-instrumentation-google-adk
  - Use dynamic version from version.py
  - Update authors to LoongSuite Python Agent Authors
  - Update homepage URL to point to specific subdirectory
- Update instrumentation-genai/README.md (remove google-adk entry)
- Update instrumentation-loongsuite/README.md (add google-adk entry)
- Update bootstrap_gen.py (remove google-adk as it's now loongsuite-specific)

This aligns google-adk with other loongsuite-specific instrumentations.
