Fix BCR presubmit pipeline (#3082)

Hopefully this resolves the following:
https://buildkite.com/bazel/bcr-presubmit/builds/9302#0193b38a-65b5-4be1-91b6-138d4ab9cc90
```

```

My assumption is that `module_path` is an extension of where the
presubmit yaml exists relative to the root one. So this should finally
enable CI to run in th eright place with the correct dependency.
