Previously we checked that "Ansible Galaxy" shows up in the html result
requesting the root of the Galaxy proxy. This now fails and looking at
the results of the fetch the title of the page is "Galaxy NG". Update
our test to check for "Galaxy NG" instead.
Additionally our content checks of actual collections are affected by an
api bump from v2 to v3. Among other things this appears to be a
completely new implementation that does not have backward compatible
support for v2 and may require authentication to use. I've commented out
our old test content for the content checks and someone will need to fix
this later.
