fix(shortcodes): use semicolon delimiter to avoid smart typography issue (#13913)

Shortcodes followed by a trailing dash were being hex-encoded in output
because Pandoc's +smart extension converts -- to en-dash, breaking the
UUID pattern match during decode.

Changed the delimiter from - to ; in the UUID-HEX encoding format to
prevent this collision with smart typography.
