Update docstring for `keys` and `vals` to cover seqs of map entries

Description

See: https://ask.clojure.org/index.php/9838/is-it-legal-to-apply-keys-vals-to-a-sequence-of-map-entries

There are multiple places where keys and vals are used on seqs of map entries (instead of concrete maps). Docstring should mention this.

We don't have a good type indicator to mean "seqs to map entries" (something like EntrySeqable) but it is a recurring thing that we have run into and maybe that would be a better solution.
