DOC: Page Not Found when redirecting to v5.3.1 'Getting Started'

[patrickmoehrke7]

Issue with current documentation:

Hi all

After accessing https://www.pymc.io/projects/docs/en/v3/pymc-examples/examples/getting_started.html (from a search engine), a banner displays near the top of the screen informing the me that the documentation I am viewing is not the latest and I should follow the hyperlink to https://www.pymc.io/projects/docs/en/v5.3.1/pymc-examples/examples/getting_started.html. However, after following the hyperlink, I receive a Page Not Found notice.

Idea or request for content:

Since there does not seem to be a matching 'Getting Started with PyMC3' page, an alternative would be to perhaps redirect to https://www.pymc.io/projects/docs/en/v5.3.1/learn.html ?

Thank you.

Regards
Patrick
