Lock `simple_form` less strictly
Lock `simple_form` less strictly

We previously supported `~> 3.2`. The regression introduced in v3.5.1 is
described at https://github.com/plataformatec/simple_form/issues/1549. We'll
need to fix our presenters to be `ActiveModel` compliant to make `simple_form`
work correctly past that version.

In the meanwhile, we shouldn't require any simple_form upgrade as part of an
upcoming Hyrax release.
