Status code safety with `RedirectStatus` and `RenderStatus`!

👇 This release introduces two new linters, courtesy of @rzane! 👇

Betterment/RedirectStatus

The redirect_to method defaults to a 302 Found, but when redirecting a POST/PUT/PATCH/DELETE
to a GET location, the correct response code is 303 See Other.

This cop requires you to explictly provide an HTTP status code when redirecting from the create,
update, and destory actions. When autocorrecting, this will automatically add status: :see_other.

Betterment/RenderStatus

The render method defaults to a 200 OK. Calling render in the create, update, and destroy
actions often indicates error handling (e.g. 422 Unprocessable Entity).

This cop requires you to explicitly provide an HTTP status code when rendering a response in the
create, update, and destroy actions. When autocorrecting, this will automatically add
status: :unprocessable_entity or status: :ok depending on what you're rendering.
