Change apartment to ros-apartment

[loed-idzinga]

Hi! I would like to propose a change in the Apartment gem. It looks like the project has been inactive for years (last commit 3 years ago) and isn't even fully compatible with Rails 6+.

I would suggestion to move to the drop-in replacement ros-apartment gem. It's not maintained by the original maintainers, but is is actively maintained.

Apartment drop in replacement gem

After having reached out via github issues and email directly, no replies ever came. Since we wanted to upgrade our application to Rails 6 we decided to fork and start some development to support Rails 6. Because we don't have access to the apartment gem itself, the solution was to release it under a different name but providing the exact same API as it was before.

This change is breaking, as that everyone who uses this also should switch to ros-apartment in the project, but the replacement works flawlessly in my own tests.
