Build documentation from clojure code and specs  #146

Desired Behavior

Code needs a good documentation.
A lot of documentation is written as function description or clojure specs.
There should be some support for building and publishing documentation from these sources.

Context

I would like to have a task that scans my clojre code and generates documentation from it.
It should look for function descriptions.
It should look for clojure spec definitions.
It should leverage existing tools.

Idea started from https://clojureverse.org/t/spec-aware-documentation-tools/6118/2 .
