Unrolled build for rust-lang#137876

Rollup merge of rust-lang#137876 - Zalathar:triagebot-matches, r=jieyouxu

Adjust triagebot.toml entries for `rustc_mir_build/src/builder/`

I only just noticed that these paths were silently broken by the renaming of `build` to `builder` in rust-lang#134365.

This is *possibly* OK to just self-approve, but I would prefer to get a second set of eyes on it just in case.
