fix sqlalchemy relations

[fozt]

When installing dependencies, version sqlaclhemy==1.4.36 is installed. It contains a bug that makes relationships to other tables not work. Even sa_relationship_kwargs={"lazy": "selectin"} parameter doesn't help. On version 1.4.35 this error disappears

How to reproduce the error with the old poetry.lock and pyproject.toml files:

1. Run commands

docker rm -f traefik-proxy fastapi_server nginx database
rm -rf db_docker
docker-compose up-build
docker-compose exec fastapi_server python app/initial_data.py

2. Go to http://fastapi.localhost/docs and authorize username: [email protected] password: admin
3. Run POST method /api/v1/team with any parameters
4. Run GET method /api/v1/team/{team_id} with parameter team_id=1
