Expose crates_vendor deps to bzlmod (#2372) 

Without this, I have been unable to update
https://github.com/dtolnay/cxx to bzlmod. When I run `bazel run
//third-party:vendor` ([this
rule](3c1bcc012f/third-party/BUILD (L3-L11)))
it failed with **"unknown repo 'cargo_bazel.buildifier-linux-amd64'
requested from @@rules_rust~0.35.0"**:

```console
ERROR: no such package '@@[unknown repo 'cargo_bazel.buildifier-linux-amd64' requested from @@rules_rust~0.35.0]//file': The repository '@@[unknown repo 'cargo_bazel.buildifier-linux-amd64' requested from @@rules_rust~0.35.0]' could not be resolved: No repository visible as '@cargo_bazel.buildifier-linux-amd64' from repository '@@rules_rust~0.35.0'

ERROR: Analysis of target '//third-party:vendor' failed; build aborted: Analysis failed
```

After this change, it works. My MODULE.bazel can be seen in
https://github.com/dtolnay/cxx/pull/1294.
