docs: conf.py: silence SyntaxWarning on js_splitter_code

The js_splitter_code string contains backslashes that Python tries to
use as escape sequence but doesn't manage to, hence the following
SyntaxWarning message:

documentation/conf.py:188: SyntaxWarning: invalid escape sequence '\p'
  .split(/[^\p{Letter}\p{Number}_\p{Emoji_Presentation}-]+/gu)

Considering that we want this to be sent verbatim to the JS, let's make
this a raw string instead.
