Too painful and too unreliable. If we want better data, we should get
better tools.

So that everything related to donations is under /donate and we don't
have to update po_translatable_pages so much.

I didn't update the numbers this time.

If I were a search engine, I wouldn't display <nav> elements in SERPs.

Also moving it below the donation messages, to make everything much
simpler.

I'll follow up on this in #18943.
