message: build(docs-infra): remove `{@searchKeywords}` from content when rendering
  Previously this inline-tag-def was returning the `doc` which is rendered
  to the output as `[Object Object]` - obviously not what is intended.
  Now it returns `''` which effectively strips the tag handler from the
  rendered output.
