fix(md-exports): clean up artifacts in API docs markdown exports

Two sources of noise leaked into the API .md exports, e.g.
`*&#x20;<!-- -->(<!-- -->string<!-- -->)*`:

- React inserts empty `<!-- -->` separator comments between adjacent text
  nodes in server-rendered output (common on component-rendered pages like
  the API docs). Drop comment nodes in the HTML->markdown pipeline; comments
  dispatch by node type, so this lives in nodeHandlers, not handlers.
- The parameter type was wrapped in an <em> with a leading space inside it,
  which remark encoded as `&#x20;`. Move the space outside the <em> so it
  serializes as a normal space.

Also bump CACHE_VERSION, since cached entries are keyed on input HTML (not on
this script) and would otherwise serve stale output after the logic change.
