* etcd3: re-enable and fix tests, add unit tests
- Add unit tests for community.general.etcd3 module (12 tests covering
state=present/absent, idempotency, check mode, and error paths)
- Fix integration test setup: update etcd binary to v3.6.9 (from v3.2.14),
download from GitHub releases, add health-check retry loop after start
- Work around etcd3 Python library incompatibility with protobuf >= 4.x
by setting PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python
- Update to FQCNs throughout integration tests
- Re-enable both etcd3 and lookup_etcd3 integration targets
Fixes https://github.com/ansible-collections/community.general/issues/322
