Support for Dragonfly Memory store

[phantomwhale]

Is your feature request related to a problem? Please describe. We are upgrading our Alchemy stack, and have got as far as Alchemy 5.1 - but this doesn't support the Dragonfly Memory Store we use in our tests

This line causing the issues is:

https://github.com/AlchemyCMS/alchemy_cms/blob/main/app/models/alchemy/picture_thumb/create.rb#L46

Describe the solution you'd like To be able to use file or memory store for Dragonfly, without Alchemy throwing errors

Describe alternatives you've considered Monkey patching DragonflyMemoryStore to have the missing server_root method, returning nil

Additional context We are hitting the following stacktrace when we create a new alchemy_picture, using the alchemy provided factories, running under Alchemy 5.1:

Failure/Error: let(:picture) { FactoryBot.create(:alchemy_picture) }

NoMethodError:
