Fix the issue in the Contribution References Documentation

Description

In the documentation Contributions page, when I tried to open the pull request hyperlink in the "Write documentation" and "Make changes in the code" sections, it is redirecting to https://www.pymc.io/projects/docs/en/stable/contributing/pr_tutorial.html#pr-tutorial page, but in actual it should redirect to https://python.arviz.org/en/latest/contributing/pr_tutorial.html#pr-tutorial

Thanks for catching the wrong link! It was an unwanted side effect of intersphinx looking at all the documentation sites available via intersphinx_mapping. As the requested target didn't exist in the ArviZ docs but it did in the PyMC ones, it ended up linking to the pymc docs.

However, we don't want to stop using cross references, to fix the issue we need to fix that particular references using the non-existent pr_tutorial target. The reason for that is that if we used urls instead of cross references we would not be able to have multi-versioned docs, every time a link that should be internal is clicked we'd always end up in latest version. But if we are browsing the docs for version 0.17 and we click on internal links we want to get to the linked page, but still for the same version we were browsing.

The ideal fix for the issue would be to add (pr_tutorial)= right above https://github.com/arviz-devs/arviz/blob/main/doc/source/contributing/pr_tutorial.md?plain=1#L1 so the pr_tutorial target exists within our own docs and the cross reference gets resolved as a link to this page.
