cleanup: Remove expired ports:
2021-07-25 devel/rubygem-paperclip: Use ActiveStorage or a fork kt-paperclip
2021-08-26 textproc/rubygem-rich: Depends on expired devel/rubygem-paperclip
devel/rubygem-paperclip: Mark port deprecated.
The port was deprecated upstream:
https://github.com/thoughtbot/paperclip
It is recommended to use for new development ActiveStorage.
For old software, a fork called kt-paperclip is available.
create USES=gem and update rubygem- ports to use it
Note that for now ports still have to have USE_RUBY=yes to use USES=gem
