Need to use "importlib-metadata<5.0" to use Celery

[whatisand]

I meet an issue when docker-compose up -d

ImportError: cannot import name 'Celery' from 'celery' (/usr/local/lib/python3.7/site-packages/celery/__init__.py)

I fix it in this way.

(at data-backend/app/pyproject.toml)

...
[tool.poetry.dependencies]
python = "^3.7"
uvicorn = "^0.11.3"
fastapi = "^0.54.1"
python-multipart = "^0.0.5"

I think origin issue were solved, but I have no idea how to apply that on this project...
