A class must be provided when mounting a model. String values are no longer supported

Describe the bug

I installed graphql_devise and ran the command bundle exec rails generate graphql_devise:install. Since that my railsapp crashes with the following error:

$ bin/rails server -b 0.0.0.0
WARNING: Zeitwerk defines the constant Generators after the directory

    /home/ubuntu/.rbenv/versions/3.0.0/lib/ruby/gems/3.0.0/gems/graphql_devise-1.0.0/lib/generators

To prevent that, please configure the loader to ignore it: 

    loader.ignore("#{__dir__}/generators")

Otherwise, there is a flag to silence this warning:

    Zeitwerk::Loader.for_gem(warn_on_extra_files: false)

I was able to fix this. the generator created the following line in config/routes.rb:

mount_graphql_devise_for 'User', at: 'graphql_auth'

I changed that to:

mount_graphql_devise_for User, at: 'graphql_auth'

Hi @whotwagner that is a very nice catch!
The generator is still using the class as a string when it would be using the class itself.

In case you want to create PR this is the related line.

Thanks so much for reporting this.

Do you think that it might be safe to simply remove the quotes or do you expect backwards compatibility issues?
