Do not self-host shields.io badges in the documentation

The privacy plugin downloads img.shields.io badges at build time; when
shields.io times out, mkdocs build --strict aborts and the
ci_test_build_documentation job fails until it is restarted. Exclude
the host like repology.org; the version badges stay current this way.
