[BUG] rbs-inline handles aliases inside of self context incorrectly

[aaronmallen]

rbs-inline does not currently correctly handle aliases in the class << self context correctly.

Given:

module MyModule
  class << self
    def foo; end
    alias bar foo
  end
end

rbs inline will produce the signature:

module MyModule
  def self.foo: () -> untyped
  alias bar foo
end

As opposed to the correct signature:

module MyModule
  def self.foo: () -> untyped
  alias self.bar self.foo
end

@tk0miya @soutaro I know this issue has been fixed but since it's still open I thought I'd mention it's currently not handling attr_* in the self scope correctly.

module Foo
  class << self
    attr_reader :logger #: Logger
  end
end

module Foo
  attr_reader logger: Logger
end
