Subject: [PATCH] Rework bracket delimiter highlight captures

Scopes them like in `brackets.scm` so that highlighting only happens
when there is an actual valid use of the delimiters; as a side effect,
this helps simplify all the sigil captures

Also includes other simplifications for embedded content in the
HEEx/HOLO/Jason sigil captures, and the doc attribute argument captures
