Add backticks for code refs in public docstrings

Wrap parameter names, literal values, and macro syntax elements in
backticks so cljdoc renders them as code. Generic nouns ("a key in
the map", "a dependency type") remain plain prose.

Declare clojure 1.12.0 in published pom

cljdoc-analyzer reads dependencies from the artifact pom; without an
explicit clojure version, the pom inherited 1.10.3 from the system
deps.edn, which doesn't know :as-alias and broke the analysis with a
fake cyclic-load error.

Bump to 3.6.2 (3.6.1 burned on Clojars)

Generate cljdoc docs for 3.6.2

3.3.0 pom
