Rustdoc unit tests not being run by Rustbuild

As far as we could tell.

Currently, running cargo test in src/librustdoc seems to work, but there are some failures:

Seems like more of an infrastructure team problem. Assigning myself, will hopefully have time before Monday.

Not yet fixed, just a preliminary patch....

[frewsxcv]

This will be fixed by #44274 ?

[Mark-Simulacrum]

It should be, yes.
