Adding in CI testing

[apeltzer]

This attempts at adding workflows for CI for the following:

• Release to PyPi
• Linting Bot that fixes linting issues upon invocation
• Linting based on our pre-commit settings
• Screenshots via rich-codex ;-) - can be used in the docs then
• Runs the unit tests we define via pytest

LGTM - Some minor comments, but the overall structure looks fine

Did you settle on a name on PyPI?

[apeltzer]

We didn't so far 😉

Unit tests still failing, something weird with quarto-cli: error: the argument '--v8-flags[=<v8-flags>...]' cannot be used multiple times

I'd suspect something was changed in a recent quarzo Version. I can look into it the next days

Yeah no worries, I'll leave this PR open and you can adjust as you like 👍🏻 Your other points were addressed hopefully, we can take it from there

Apart from the name lgtm 👌

Stripped it down a bit (see #22 for follow-up).
Autofixing seems to work, checks are passing now.

Need to settle on a name for pypi, but we could even do so after merging this.
