Add uv project install instructions to docs

[cfe316]

Resolves #1680 .

This method is under the On Your Local Machine section but it also works on clusters.

I'm not sure how to preview any documentation. Is there a way?

[dpanici]

running the command make html in the docs folder should make the docs locally and you can view them in the docs/_build folder (I think)

but you can a so just wait for the docs action to complete here and check it there

@cfe316 I have some minor comments, but since uv is relatively new, I think it is worth having some additional explanations.
