vim-patch:36d01cf: runtime(typst): do not highlight code blocks and raw text

Similar to markdown syntax, by default do not highlight raw and code blocks.

Syntax highlighting groups are still in place so it is possible for
users to add their own if needed.

- typstMarkupRawInline
- typstMarkupRawBlock
