Doc link fix

[cvanelteren]

Updates the docs to ensure that the links are visualized. It further also improves styling to use UltraPlot in text and ultraplot in code.

Addresses #90

[cvanelteren]

for me later: I used:

(`~matplotlib(?:\.[A-z]+)*)(\.[A-Z][a-z_]+`)

[cvanelteren]

Note to self: autoapi and autodoc don't play nice together.

[cvanelteren]

Ok I wasted a couple of hours on this and it turned out to be autoapi -- which I added some time ago.

[cvanelteren]

Note the added function in conf.py was necessary to get it to expand the docstrings.

[cvanelteren]

I think I will fix this by going back to main and only adding the conf.py. Docs are building fine locally, but not on the action. Furthermore, the submitted changes are not necessary I think. Other than the first one.

Things like :class: etc. are still not applied everywhere. That's OK, but I thought I would mention it.

I flagged a few changes we should rollback.

[beckermr]

We need to be updating this file in our PRs. Let's open an issue to backport the updates for the versions not in here.

[cvanelteren]

Done, and thanks ;-).

[cvanelteren]

Could be that we have to pin sphinx to 8.1.2. Seeing some errors pop-up locally.

[beckermr]

Changes look good. When you are happy with the build, merge away!
