ActiveSupport::Messages::Metadata has wrong type for ActiveSupport 7

[richardboehme]

In ActiveSupport 7 ActiveSupport::Messages::Metadata is a module while in ActiveSupport 6 it's a class. As the types for ActiveSupport 7 are symlinked to the generated rbs of ActiveSupport 6 the type is wrong.

It seems like there is an ongoing discussion in #788 about how to manage Rails' types in the future, so if this ticket is unnecessary/will be fixed with the new approach, feel free to close this issue.
