build: use nox for tests and docs

[12rambau]

Fix #239

In this PR I added a few configurations to build unit tests and documentation pages using nox. It creates isolated environments to ensure that the build will work when send to RDT. It's also the first step toward unit testing.

• create 2 nox sessions: "lint" to run the pre-commits (assuming it will be merged) and "docs" to create the documentation in a docs/_build folder.
• remove makefiles as they are nicely replaced by nox -s docs
• add the nox-produced files to .gitignore
• create a doc set of extra_requires to have everything needed for the documentation
• set up a .readthedocs.yaml file so that the documentation is built using the correct env

As I need to check the RDT build there will surely be test commits, I assume you will just squash my PR so I'm just sorry for the noise.

@maartenbreddels, @mariobuikhuizen I would like the doc to be build on main (at least latest) but when I install in dev mode there are many npm command that start. Of course it wasn't an issue before because RDT was build from the pipy version.
Would you have any guidance ?

[maartenbreddels]

I never build on rtd, because there wasn’t enough memory. Why do you want to do that?

[12rambau]

If I want to work on the API build in #238 I would like to make sure latest is on track with main. So I would need to run: pip install .[doc]

I think you should install Jupyter lab to be able to build

thanks @maartenbreddels for the tips. The complete solution was "install jupyterlab before the lib to enable the build of jupyter extentions when npm install will be called from the js folder to execute webpack scripts".

with the pre-install job, it works like a charm. This is then ready for review

@maartenbreddels things were working just fine when I finished my PR: https://readthedocs.org/projects/ipyvuetify/builds/19602806/ but now I get NPM warnings/errors everywhere: https://readthedocs.org/projects/ipyvuetify/builds/19959839/

Is there something to change there ? like node version ? python version ?

[12rambau]

sorry for the noise. I made many tests from RDT side. I hope they will help me find a solution from their side: readthedocs/readthedocs.org#10223

[mariobuikhuizen]

This PR now depends on the fix in: #259

@mariobuikhuizen I rebased on the current master and solved the remaining RDT related issue. I think this one is also ready to go.

Looks good Thanks!
