Use Rails global constant

[RStankov]

When I updated my application to Ruby 3.2.2 I start getting the following error

 undefined method `gem_version' for Flipper::Rails:Module (NoMethodError)

From this line

COLOR_OPTIONS = if Rails.gem_version > Gem::Version.new('7.0.99')

The reason is that Rails in this context is mistaken for Flipper::Rails instead of the global Rails.

Weird that it would do that. Doesn't seem to be happening for me on 3.2.2. That said, I don't think this can hurt anything and maybe it helps.

@bkeepers any thoughts?

@RStankov Are you by chance using the old flipper-rails gem? We don't define Flipper::Rails anywhere, so I'm not sure where else that would be coming from.

[RStankov]

Yes, I'm using flipper-rails. I didn't know it isn't needed anymore

When I remove it, it fixes the issues and everything seems to work :)

[bkeepers]

@RStankov Great! flipper-rails was not an official gem and is deprecated.

Closing this since I don't think it's needed, but let me know if anyone feels otherwise.
