fix(test_docs): deterministic remote test

The remote test relied on a full repo clone that included all branches, which
isn't guaranteed, especially in CI environments and when using repo forks. Use
the cloned repo instead, since it will still test the desired functionality but
will always have the necessary upstream branch.
