Consider: Switching to ActiveStorage from Paperclip

[matthewford]

Pitch

Paperclip has been deprecated https://thoughtbot.com/blog/closing-the-trombone, and while there are efforts to maintain it via kt-paperclip, it would make sense to switch to ActiveStorage.

Doing so would make the switch to vips #20269 much simpler, as ActiveStorage uses https://github.com/janko/image_processing which supports both ImageMagick and vips.

Some guides on how to switch:

As ActiveStorage is part of Rails core it will be better supported by the community.

Motivation

All servers.

There's already an open issue for this at #7414, not much activity since 2018 however

This is indeed a duplicate of #7414.
