Subject: [PATCH 1/2] Update the PDF.js web page to link to both versions of
 the demo viewer (PR 11241 follow-up)

Rather than adding two buttons, it seems easier to simply link to the relevant section of the README instead (since it also means fewer things to keep up-to-date).

Subject: [PATCH 2/2] Attempt to improve/clarify the "Online demo" section of
 the README

Hopefully this will help, now that there's *two* version of the viewer available.
