Auto merge of rust-lang#130724 - compiler-errors:bump, r=Mark-Simulacrum

Bump stage0 to beta-2024-09-22 and rustfmt to nightly-2024-09-22

I'm doing this to apply the changes to version sorting (rust-lang/rustfmt#6284) that have occurred since rustfmt last upgraded (and a few other miscellaneous changes, like changes to expression overflowing: rust-lang/rustfmt#6260). Eagerly updating rustfmt and formatting-the-world will ideally move some of the pressure off of the beta bump which will happen at the beginning of the next release cycle.

You can verify this is correct by checking out the changes, reverting the last commit, reapplying them, and diffing the changes:

```
git fetch [email protected]:compiler-errors/rust.git bump
git checkout -b bump FETCH_HEAD
git reset --hard HEAD~5
./x.py fmt --all
git diff FETCH_HEAD
# ignore the changes to stage0, and rustfmt.toml,
# and test file changes in rustdoc-js-std, run-make.
```

Or just take my word for it? Up to the reviewer.

r? release
