Auto merge of #25898 - jdm:rustup, r=asajeffrey

Update to 3/4 nightly rustc.

The comment changes address a bunch of new warnings that look like this:
```
warning: unused doc comment

    = help: to document an item produced by a macro, the macro must produce the documentation as part of its expansion
