flask:3.0.0 incompatible with flask-restx:1.1.0 seems to break the ansibledb server

[bmorris53]

My docker container during an automated build updated flask from 2.3.3 to 3.0.0 and am now getting the following traceback when attempting to redeploy the ansibledb pod with the latest container running flask 3.0.0. Looks like flask-restx is trying to use something that is no longer included in the base flask package: https://github.com/python-restx/flask-restx/issues/567

I'll be forcing the requirements.txt to use v2.3.3 for now. Just wanted to let you know of the issue.

Maybe update requirements.txt to the following in order to ensure compatability between flask and flask-restx until restx is updated to 1.1.1.

pymongo
Flask==2.3.3
python-dotenv
gunicorn
flask_swagger_ui
flask_restx==1.1.0
