DOC: "View this page" links broken in API reference

[j-bowhay]

The show this page in the top right corner of the above takes you to a dead link

looks like this problem is restricted to pages generated with sphinx.ext.autodoc

@j-bowhay could you read pydata/pydata-sphinx-theme#1269 (comment) and let me know if you have a preference?

IMO 3 > 1 > 2

I had a look at this for a bit but couldn't get it working. PR welcome which implements either option 3 or 1 I would say.
