Upgrade Dependencies to make the package compatible with Flask >=2.3

[utnapischtim]

General

Flask 2.2 deprecated the variable _app_ctx_stack (and a lot of other stuff). Flask 2.3 removed most of the things 2.2 deprecated. _app_ctx_stack was heavily used in a lot of packages so also in the SQLAlchemy packages. Only the newest versions remove this usage so all dependencies have to be updated.

The deprecation warning looks like:

env/lib/python3.9/site-packages/flask_sqlalchemy/__init__.py:302: DeprecationWarning: '_app_ctx_stack' is deprecated and will be removed in Flask 2.3. Use 'g' to store data, or 'app_ctx' to access the current context.
  queries = _app_ctx_stack.top.sqlalchemy_queries

Problems

• With SQLAlchemy 2.0 the definition of a Session changed slightly

NOTES

• support for flask-sqlalchemy >= 3.1.0 pallets-eco/flask-alembic#3 how could that be merged and released?
