Rollup merge of rust-lang#124437 - linyihai:doc-link-typeck, r=compiler-errors

doc: Make the `mod.rs` in the comment point to the correct location

The origin `mod.rs` had moved to `rustc_hir_analysis::check`, but the annotation doesn't point to it.

See [the origin PR](https://github.com/rust-lang/rust/pull/61857/files#diff-b65997b61ccd8d8e08238c925d631207671aca506e93ce7c5cfa0bec134c0a8e).
