Think about adding roxygen topics for "special" functions

I got a question in the workshop about the fact that you can't do ?drift and pull up any information on the drift() special. I get that this isn't a "real" function, but I wonder if you could somehow add a topic page so that ?drift takes you to the ?NAIVE page so you can still see something like this https://fable.tidyverts.org/reference/RW.html#specials

If drift() can be used in multiple different model types, maybe it can be a landing page specific to drift that can let you then click through to whatever specific model you are interested in using drift with

Inspect the existing roxygen documentation behind the ?NAIVE page and the special-function references linked from the issue, then check how ?drift currently resolves. Decide whether drift needs a standalone landing topic or links into model-specific topics; done means ?drift opens useful documentation for the special and the relevant model paths remain discoverable.
