Add support for Ruby 3.1 shorthand hash syntax

[nickjer]

Ruby 3.1 has a new shorthand for its hash syntax. So you can now do things like...

def create
  @my_model = MyModel.new(value:)
  # ...
end

def value
  'value'
end

Unfortunately, for the above scenario I get the following linter warning remove unused methods (MyController#value) even though the method #value is being used.

@nickjer it's fixed in version 1.23.0
