Set the generics of the struct based on the type of its attributes

[rhiroe]

Account = Struct.new(
  :id,    #: Integer
  :email, #: String
)

This Ruby code generates the following RBS code:

class Account < Struct[Integer | String]
  attr_accessor id(): Integer

  attr_accessor email(): String

  def self.new: (?Integer id, ?String email) -> instance
              | (?id: Integer, ?email: String) -> instance
end
