Hi @TymoshokDmytro I see that some doc files still have 3.7.9 version. Is it ok ?

grep -rl "3.7.9" --exclude-dir={node_modules,venv,.venv} --exclude="*.svg" ./docs/
./docs/.gitbook/assets/newsourcetutorial_plop.gif
./docs/contributing-to-airbyte/python/tutorials/cdk-tutorial-python-http/0-getting-started.md
./docs/understanding-airbyte/tech-stack.md
./docs/tutorials/transformation-and-normalization/transformations-with-dbt.md
./docs/tutorials/tutorials/build-a-connector-the-hard-way.md

some files in ./airbyte-integrations/bases/
./airbyte-integrations/bases/base-python/docs/tutorials/http_api_source.md
