Typst reader: handle inline-level show rules on block content.

Typst allows things like `smallcaps` to be applied to block-level
content like headings.  This produces a type mismatch in pandoc,
so before processing the output of typst-hs, we transform it,
pulling the block-level elements outside of the inline-level
elements.

Closes #11017.
