Issues with Documentation

• void needs to be added to the type map
• Some types, like CacheClass or Iterable or HashableObject are missing
• Extends need to be in doc-kit format
• API docs need source frontmatter (blocked by feat: sponsorship & sidebar improvements #131)
• https://webpack-doc-kit.vercel.app/api/v5.x/chunks/types (maybe upstream)

@avivkeller, regarding the missing types:

• void & Iterable: These are excluded because we enabled excludeExternals: true in the previous PR docs: add typedoc-plugin-missing-exports #109 (since they are native JS types).

• HashableObject: It is completely unexported. We previously discussed the TypeDoc option to include unexported types placeInternalsInOwningModule: true.

• CacheClass: It is exported as Cache, but referenced in JSDoc as CacheClass (an alias mismatch).

So, to solve that, we can use solutions in description of PR #109, but the alias thing, I think that the typedoc reflection will has a solution, WIP
