* feat: Enable `PDFDownloadLink` to Receive Anchor Props

Changes:
- Pass ALL anchor tag props to the rendered anchor
  element -- EXCLUDING the reserved `href` attribute.
- Improve the `onClick` type of `PDFDownloadLink`.
- Minor cleanup in related files.

* feat: preserve doc var

* fix: preserve blank line
