Rollup merge of #104332 - Elarcis:maybe_uninit_doc_fix, r=m-ou-se

Fixed some `_i32` notation in `maybe_uninit`’s doc

This PR just changed two lines in the documentation for `MaybeUninit`:

```rs
let val = 0x12345678i32;
```
was changed to:
```rs
let val = 0x12345678_i32;
```
in two doctests, making the values a tad easier to read.

It does not seem like there are other literals needing this change in the file.
