fix inline documentation about is_greater_than in validate_comparison_of matcher

[jeduardo824]

This PR fixes the initial example the inline documentation of the validate_comparison_of matcher. In the example, the matcher is using greater_than(...) in the tests, but it is actually is_greater_than(...).

Hey, @jeduardo824, great find!

I noticed another one at

shoulda-matchers/lib/shoulda/matchers/active_model/validate_comparison_of_matcher.rb

Line 49 in a078b46

# should validate_comparison_of(:number_of_dependents).greater_than(0).on(:create)

Could you include this in your pull request too?

Thanks a lot for your contribution!
