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.

To Reproduce
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

Expected behavior
It should redirect to https://python.arviz.org/en/latest/contributing/pr_tutorial.html#pr-tutorial.
