core doesn't use Record<string, unknown> for public API (elastic#41448)

* core contracts don't use unknown to support type assignment

limitations of https://github.com/Microsoft/TypeScript/wiki/Breaking-Changes#-k-string-unknown--is-no-longer-a-wildcard-assignment-target

* regenereate docs

* remove type over-write
