fix: elasticsearch

[sergerdn]

• Create a new docker-compose file to start an Elasticsearch instance for integration tests.
• Add new tests to test_elasticsearch.py to verify Elasticsearch functionality.
• Include an optional group test_integration in the pyproject.toml file. This group should contain dependencies for integration tests and can be installed using the command poetry install --with test_integration. Any new dependencies should be added by running poetry add some_new_deps --group "test_integration"

Note:
New tests running in live mode, which involve end-to-end testing of the OpenAI API. In the future, adding pytest-vcr to record and replay all API requests would be a nice feature for testing process.More info: https://pytest-vcr.readthedocs.io/en/latest/

Fixes #2386
