Remove unneccesary step that's making workflow fail (#81164)
This step was causing the front-sync job to fail. I'm not totally sure
how it was working before, some other workflow must have logged logged
in at some point. This is just a debug step anyway, so I think we can
delete it. **I confirmed that the next step worked just fine.** We could
also add a step that runs `gh login` if we think it would actually be
useful.
