Upgrade versions in setup.py

[UlrichB22]

Change dependencies to upgrade to newer versions as discussed in #1109

• Flask 2.0.3
• Flask-Script 2.0.5
• Jinja2 3.0.3
• MarkupSafe 2.1.2
• Werkzeug 2.1.2

Hopefully it also fixes #1333, my tests with ./m docs run successfully in Debian 11.

Please support with testing in different environments.

Works on Windows 10 with Python 3.10. But a freshly created venv still has sphinx-rtd-theme version 0.5.1 even though docs/requirements says "sphinx-rtd-theme==1.1.1".

Still fails on readthedocs with "sphinx-rtd-theme==1.1.1 ". See readthedocs/sphinx_rtd_theme#1323

ERROR: Cannot install -r docs/requirements.txt (line 4) and docutils>=0.18.1 because these package versions have conflicting dependencies.

The conflict is caused by:
The user requested docutils>=0.18.1
sphinx-rtd-theme 1.1.1 depends on docutils<0.18

To fix this you could try to:

1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

Upgrading sphinx to 1.1.1 fails. Upgrading sphinx-rtd-theme to 1.2.0rc3 Succeeds,

[UlrichB22]

Is it ok to temporarily pin sphinx-rtd-theme to 1.2.0rc3 in requirements.txt?
Version 1.2.0 seems to be coming soon.

[RogerHaase]

Yes, but installing sphinx-rtd-theme to 1.2.0rc3 still downgrades docutils to 18.1.

I am thinking it is time to find another theme. The theme was changed from classic to sphinx-rtd-theme on 2016-02-03: cf48fcc because it had better support for smartphone screen sizes.
