Add stardoc rule documentation to docs/ Also ensure (via a test) that this rule documentation is up to date.
Stardoc is a documentation generator for Bazel build rules written in Starlark.
Stardoc provides a Starlark rule (stardoc, see documentation) that can be used to build documentation for Starlark rules in Markdown. Stardoc generates one documentation page per .bzlfile.
Stardoc is a replacement for the deprecated “Skydoc” documentation generator.
See Skydoc Deprecation for details on the deprecation and migration details.
