Add rustfmt 2024 reformatting to git blame ignore

rust-lang/rust#130724 essentially reformatted the world, so we should add it to the git blame ignore list.

Tested with `git blame compiler/rustc_abi/src/lib.rs -L1137,1146`. I first thought that I have to ignore the merge commit, but it seems like the actual commit that did the reformatting should be ignored instead.
