Fix Python Dependencies

The main purpose of this PR is to update the Python Motor package to version 3.6.0 to resolve pymongo compatibility issues after the release of pymongo 4.9.X
Also updates the other Python packages
Updates FastAPI to 0.113.0

Note:

With FastAPI >0.113.0 the test_apply_successfully_without_resume pytest fails because the /apply route doesn't seem to like being passed an empty resume file with file name as an empty string "" for the resume parameter. This is seemingly caused by the resume parameter being declared of type Optional[UploadFile] and with FastAPI versions >0.113.0, the empty resume files being sent is seen as of type str. Will attempt to take a look at this in another issue.
