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.

tidy: add triagebot checks

Validates triagebot.toml to have existing paths:

`[mentions."*"]` sections, i.e.
```toml
[mentions."compiler/rustc_const_eval/src/"]
```
or
```toml
[assign.owners]
"/.github/workflows" = ["infra-ci"]
```
or

```toml
trigger_files = [
 "src/librustdoc/html/static/js/search.js",
 "tests/rustdoc-js",
 "tests/rustdoc-js-std",
 ]
```
Looked at rust-lang#137876 and implemented check.
