I'm not sure what this spec achieves, that to_set works even if set isn't required?
It can't really test if to_set does or not require/autoload Set under the hood.
So I'm hesitating whether this is worth keeping, partly because ruby_exe tests are slow and the value seems minimal here, since Set being always available is or should be tested elsewhere.

It was a copy-paste from core/enumerable/to_set_spec.rb, but that one has been removed in commit d871546
I think these specs started as a way to test the autoload in Ruby 3.2, but since Ruby 3.2 is now the minimal version and we don't require set anywhere in the specs, it should probably be okay to just remove it.
