Remove Paperclip support

[chrean]

Paperclip is deprecated and unsupported, with ActiveStorage being the recommended substitute.
Although some shops won't have issues in the short term, they will eventually face problems when updating the stack since Paperclip does not support newer versions of Ruby and Rails.
Our major concern is providing users with a solid migration path; however, we cannot see a zero-effort migration.

Just for reference, we have already done it in the past.
This is the required effort to run the migration https://gist.github.com/jmevans0211/b9abb28ed51b13a46df451e87c901767.
It's not so straightforward as mentioned in the documentation, especially, when different services S3, imgix etc.. are involved.

It seems the link you shared isn't working. Could you please refresh it or provide an updated one? It would be really helpful to understand the complexities involved. Thanks for your help!

@ashgaliyev, the link is not available anymore, but in the meanwhile, I found a really interesting article talking about the migration from paperclip to activestorage, and this approach looks way better than the other.

I hope it will help you with the migration, if you have any doubts feel free to reach out.
