rbs files with untyped block type/method type parameters causes error in `bin/test`

reproduction:

1. run bin/init_new_gem foobar (version: 0.0)
2. edit gems/foobar/0.0/foobar.rbs as below

module Foobar
  def foo: (?) -> untyped
end

3. running bin/test gems/foobar/0.0, raises an error as below:

 => Failure 🚨

# Failed gems
gems/foobar/0.0

Reproduce the failure with bin/init_new_gem, the sample gems/foobar/0.0/foobar.rbs signature, and bin/test gems/foobar/0.0. Start by tracing the validation error shown from RBS 3.5.1 in rbs/method_type.rb and cli/validate.rb. Done means bin/test handles the untyped signature without raising and the gem passes validation.
