Description
In my opinion, subs aren't as helpful if we don't use them consistently. In https://github.com/elastic/elastic-docs-vscode/pull/2, we added inline warnings when an author hard-codes the value of a sub instead of using the sub key, which provides a light-touch way to encourage consistent use of subs and weed out unnecessary subs without introducing a bunch of errors.
However, there are some subs that are likely unnecessary, like api-examples-title: Examples, that should be removed from docset.yml. We should go through repo-level subs in this repo (and others) and eliminate any unnecessary subs.
