Enable class names for factories (#6700)

* ☑️ Better allow downstream apps to reuse factories

Prior to this commit, a downstream implementation that re-uses a factory
cannot change it's inheritance.

In my experiments, I am unable to modify a factory's parent via
FactoryBot's current implementation.  This means that in a Hyku
application that has it's own AdminSet, FileSet, and Collection models,
I cannot re-use the `:hyrax_admin_set`, `:hyrax_collection`, and
`:hyrax_file_set` factories.  The problem emerges when I re-use a Hyrax
factory that then calls a Hyrax factory (e.g. the permission_template
factory can create a `:hyrax_admin_set`).

With this commit, I downstream applications can more easily re-use
factories.  I need the antics of sniffing out ancestry because of Hyrax
configurations under test.  Namely when we're testing wings the
Hyrax.admin_set_model is `"AdminSet"`; which breaks all sorts of things.

* ☑️ Remove hyrax/specs/factories

In my downstream testing this was creating absolute mayhem with
auto-loading.  Once I've settled on the pattern, I'll document how to do
this.

* 💄 endless and ever appeasing of the coppers
