Is your feature request related to a problem? Please describe.

For a line like this, which starts with #: I get a line length lint error:

#: (?date: Date, foobar: BigDecimal, ?foobarbaz: BigDecimal, ?foobarbazqux: BigDecimal, ?records: Array[Foo::Bar], ?calculate_something: bool) -> Foo
def foo(date:, foobar:, foobarbaz: 1, foobarbazqux: 1, records: [], calculate_something: true)
  # code
end 

Describe the solution you'd like

I would love to see a setting on Layout/LineLength to automatically ignore lines that start with the #: syntax.

Describe alternatives you've considered

Rewriting the inline RBS signature to be multiple lines, but it only appears to support single line syntax right now, unfortunately.
