Upin xclim, package health

[Zeitsperre]

Description

This PR does the following:

• Unpins xclim's version
• Sorts the environment.yml and the setup.py metadata (specifies Python3.11 support)
• Adds --color=yes and --verbose to pytest calls
• Adds a few relevant pre-commit hooks, as well as updates existing versions
• Removes nb_black (unmaintained)
• Fixed a few flake8 violations and RuntimeWarnings
• Employs the mamba-org/setup-micromamba Action across all CI workflows, with caching
• Cleans up the environment files for all build variants (migrating pip libraries to conda-forge equivalents, sorting alphabetically, pinning versions unilaterally).
• ReadTheDocs now uses the mambaforge image to make better use of conda
• @aaronspring: fix tests or silence tests

There are a few really annoying/loud warnings coming from xclim. I've opened an issue to handle one of the worst offenders: Ouranosinc/xclim#1489. A few other warnings coming from xclim have already been dealt with in the master branch and will be muted in v0.46.0.

I've tried my best to clean things up here without breaking much. It feels to me a bit easier to maintain the CI and environments now. The same six tests are failing across builds, but I have no idea how to address them (perhaps these will be tackled in #831).

The documentation is building with hundreds of warnings; This would definitely need to be fixed in another Pull Request.

I need to move on to other projects for the time being, but hopefully this PR helps a bit!

Getting a core dump now

One time it worked for maximum deps without a python version https://github.com/pangeo-data/climpred/actions/runs/6678923589/job/18150486165 but failed for the ones with a python version in the name but I don't even see where the one without python version in name is configured ...

exchange netcdf4 for h5netcdf in env seems to work

[aaronspring]

Finally! It took a while but now I resolved all issues and CI passed.
Any further changes before I merge? @mathause @Zeitsperre

[aaronspring]

Fixes #815 ?

[Zeitsperre]

Should this be replaced with h5netcdf?

[aaronspring]

Locally it works with netcdf but I will add a comment here

[Zeitsperre]

That's fantastic! I'm away from the office for the next few days, but everything looks good on my end!

[mathause]

Looks good! Thanks for all your work!
