Malli generates incorrect clj-kondo spec for :fn schemas

[camsaul]

Contrived example:

(mx/defn x [y :- [:fn vector?]]
  y)

(x [:x])
;; => Expected function, received vector

The generated Kondo fig is incorrect:

{x {:arities {1 {:args [:fn], :ret :any}}}}

This should get fixed by #851

I think I have an issue related to this, I tried to specify data with a predicate and clj-kondo believes I should provide a function but my predicate checks if it is a string starting with "SKU-". If it can't infer that the type is a string it could at least type it to any right ?

FYI ran into this myself lately, took a stab at fixing this w/ #987 .
