Fix dandi-staging alias: also patch get_instance to remap to dandi-sandbox

dandi >= 0.74.0 has an explicit ValueError check rejecting 'dandi-staging'
after the known_instances lookup. Patching known_instances alone isn't
enough. Now also patch dandi.utils.get_instance to remap 'dandi-staging'
to 'dandi-sandbox' before the check runs.
