`_app_ctx_stack.top` is deprecated and will be removed in Flask 2.3

I'm getting the following warning:

venv/lib/python3.9/site-packages/flask_sqlalchemy_session/__init__.py:11
venv/lib/python3.9/site-packages/flask_sqlalchemy_session/__init__.py:11
  venv/lib/python3.9/site-packages/flask_sqlalchemy_session/__init__.py:11: 
DeprecationWarning: '_app_ctx_stack' is deprecated and will be removed in Flask 2.3.
    from flask import _app_ctx_stack, current_app

These are the relevant notes from Flask's 2.2.0 release notes:

• The app and request contexts are managed using Python context vars directly rather than Werkzeug’s LocalStack. This should result in better performance and memory use. #4682
  • Extension maintainers, be aware that _app_ctx_stack.top and _request_ctx_stack.top are deprecated. Store data on g instead using a unique prefix, like g._extension_name_attr.
