docs(gen_help_html.lua): h4 pseudo-heading layout #30609

Problem:
The right-aligned tag "pseudo-heading" layout mushes together with the
left-aligned text. This is especially messy in a narrow viewport.

Solution:
Put a `<br>` on it. This is a hack until tree-sitter-vimdoc recognizes
these pseudo-headings.
