Duplicate intra-doc link errors in `std`

[camelid]

I found this while working on #78093:

error: unresolved link to `use`
  --> library/std/src/keyword_docs.rs:23:74
   |
23 | /// Other places `as` is used include as extra syntax for [`crate`] and [`use`], or to change
   |                                                                          ^^^^^ the module `std` contains no item named `use`
   |
   = note: `-D broken-intra-doc-links` implied by `-D warnings`
   = help: to escape `[` and `]` characters, add '\' before them like `\[` or `\]`

error: unresolved link to `use`
  --> library/std/src/keyword_docs.rs:23:74

23 | /// Other places `as` is used include as extra syntax for [`crate`] and [`use`], or to change
   |                                                                          ^^^^^ the module `std` contains no item named `use`
   |
   = help: to escape `[` and `]` characters, add '\' before them like `\[` or `\]`

Not sure how to reproduce; it's probably some weird state issue.

Another instance of this:

error: `f32` is both a module and a builtin type
   --> library/std/src/primitive_docs.rs:834:12
    |
834 | /// `f32`](f32) or [Wikipedia on double precision
    |            ^^^ ambiguous link

    |

    |            ^^^^^^^
help: to link to the builtin type, prefix with `prim@`

error: aborting due to 2 previous errors

I think this might be a duplicate of #77681.

[camelid]

I think I ran into this the other day with a different project and I don't think it was the same issue as #77681. It's hard to make repros :/

[jyn514]

@camelid have you run into this recently? I'm inclined to close otherwise.

[camelid]

I have not, though it's possible that the original sample from the standard library still reproduces.

[jyn514]

Ok. I'm going to close this until you run into it again, it's not really actionable right now.
