Prep gem for Ruby 4.0

[aaccensi]

Context

In an ongoing effort to prepare the internal gems for the upcoming Ruby4/Rails8 update, we updated their semaphore checks to use versions 3.3 and 4.0. Then run their RSpec tests locally against this 2 versions to identify any early issues (at gem level) and fix them.

Implemented changes

• refinery: Update Ruby version checks to 3.3/4.0
• fever: Update Ruby version checks to 3.3/4.0
• merit: Update Ruby version checks to 3.3/4.0 and add csv dependency
• atlas: Update Ruby version checks to 3.3/4.0 and lockfile/dependencies for Ruby 4.0
