fix(docs): send presenter state to the page's own origin - #2010

Conversation
The deck posted every slide update to the presenter window with a wildcard target, so a presenter window navigated elsewhere would still receive the state and speaker notes. Both decks now target the page's origin, as the other presenter messages already do.
