Handle the other two part warning from Ruby 2.7

[casperisfine]

Followup to: #45

There is a second type of multipart warning I missed:

def foo(hash, a: 1, b: 1)
  ...
end

foo(bar: 42)

In this case Ruby 2.7 complains because it's ambiguous wether you expect to pass the first parameter as a hash, or if you expected to pass keyword args.

Ruby expects you to call the method with explicit brackets:

foo({ bar: 42 })

Or better avoid this kind of method signatures.

Feel free to ignore the suggestion.

Suggested change

	# Ruby 2.7 has two warning for improper use of keyword arguments that is sent as two parts
	# Ruby 2.7 has two warnings for improper use of keyword arguments that are sent in two parts
