Upgrade to Python3.11 + update dependencies versions

While starting gutenberg2zim on my Mac for the first time in a fresh venv, I got the following error :

Traceback (most recent call last):

ImportError: cannot import name 'soft_unicode' from 'markupsafe' (/Users/benoit/Repos/gutenberg/.venv/lib/python3.9/site-packages/markupsafe/__init__.py)

Searching the Internet indicates that downgrading markupsage to 2.0.1 solves the issue

pip install markupsafe==2.0.1

I confirm it solves the issue on my side. Probably linked to the fact that Jinja2 version is pretty old (2017).

Some details :

Python 3.9.12
pip 22.3.1
MacOS Monterey 12.6

Yes, we had this on all Jinja-using scrapers. gutenberg hasn't received an update in a long time.

[benoit74]

I would suggest to change the title and update all deps, does it makes sense for you? I can work on it and submit a PR.

@benoit74 Definitly, see openzim/overview#13 as well.
