gemspec is missing required_ruby_version

[kyrofa]

Closely related to thoughtbot/factory_bot#1614: the gemspec doesn't claim any specific Ruby compatibility, but it's pretty clear from commits like 499635f that only specific ones are supported. The gem will be far easier to use if the gemspec can make that clear.

As factory_bot defines a required Ruby version and factory_bot_rails has a clear dependency on it, there is no need to keep it redundant with it's own Gemspec. Avoiding this also ensures the specifications can't diverge.

[kyrofa]

This gem includes Ruby code, though. It should have an opinion (and test matrix) on the Ruby versions with which its code is compatible. It doesn't matter if Factory Bot is compatible with Ruby 3.2 if Factory Bot Rails has code that is NOT compatible with Ruby 3.2, for example. The specs SHOULD diverge, in such a case.

I disagree that there's any case they should diverge but I see no disadvantage of adding the minimal Ruby version as with factory_bot to the specification.
