fix(bazel): protractor rule does not run spec files with underscore (#28022)
fix(bazel): protractor rule does not run spec files with underscore (#28022)

There are various e2e tests with the `_spec.ts` suffix in the Angular project. Currently the protractor Bazel rule does not pick up these files and just ignores them. Since underscore is commonly used, we should support this.

Needed for the conversion fo the `examples` to Bazel.
