### Description



```

from pydantic.typing import evaluate_forwardref, get_args, get_origin

ImportError: cannot import name 'get_args' from 'pydantic.typing' (/Users/yfeng/Library/Caches/pypoetry/virtualenvs/aips-cq-resource-api-F3u0rVOe-py3.8/lib/python3.8/site-packages/pydantic/typing.cpython-38-darwin.so)

In `fastapi=0.95.2`, the dependency on `pydantic` is [here](https://github.com/tiangolo/fastapi/blob/0.95.2/pyproject.toml#L45) which indicates `pydantic=1.6.2` can be used. But `get_args` is only available in `pydantic>=1.7`, while `pydantic=1.6.2` [code](https://github.com/pydantic/pydantic/blob/v1.6.2/pydantic/typing.py) doesn't have this
