Enable/Disable Docs.MS Publishing Per Artifact

[scbedd]

The ability to retarget a repo based on ci.yml is already there, but I neglected to support disabling certain packages. This is due to the fact that even management packages need to be documented.

Well, turns out the spring starters aren't valuable from a artifact documentation point of view.

So we need a methodology to enable/disable the update-docs-ci run specifically in update-docs-metadata.yml. The readme updates are still judged to be valuable.

Sync with @scbedd, @weshaggard, will update a new artifact.options.skipDocMs option in condition step.
