fix(docs-html): update parser

- Improve generated HTML by updating parser which includes fixes for
  single "'" and single "|":
  https://github.com/neovim/tree-sitter-vimdoc/pull/31
- Updated parser also fixes the conceal issue for "help" highlight
  queries https://github.com/neovim/tree-sitter-vimdoc/issues/23 by
  NOT including whitespace in nodes.
  - But this means we need to restore the getws() function which scrapes
    leading whitespace from the original input (buffer).

that you don't want auto-wrapped. Lists are always rendered with "flow"
(soft-wrapped) layout instead of preformatted (hard-wrapped) layout common
in legacy :help docs.
- Limitation: currently the parser https://github.com/neovim/tree-sitter-vimdoc
does not understand numbered listitems, so use a bullet symbol (- or •)
before numbered items, e.g. "- 1." instead of "1.".
- Separate blocks (paragraphs) of content by a blank line(s).
- Do not use indentation in random places—that prevents the page from using
"flow" layout. If you need a preformatted section, put it in

`/lua/?/init.lua` to each runtimepath, all unique `?`-containing suffixes of
the existing |package.cpath| are used. Example:
1. Given that
- 1. Given that
- 'runtimepath' contains `/foo/bar,/xxx;yyy/baz,/abc`;
- initial (defined at compile-time or derived from
`$LUA_CPATH`/`$LUA_INIT`) |package.cpath| contains
`./?.so;/def/ghi/a?d/j/g.elf;/def/?.so`.
2. It finds `?`-containing suffixes `/?.so`, `/a?d/j/g.elf` and `/?.so`, in
order: parts of the path starting from the first path component containing
question mark and preceding path separator.
3. The suffix of `/def/?.so`, namely `/?.so` is not unique, as its the same
as the suffix of the first path from |package.path| (i.e. `./?.so`). Which
leaves `/?.so` and `/a?d/j/g.elf`, in this order.
4. 'runtimepath' has three paths: `/foo/bar`, `/xxx;yyy/baz` and `/abc`. The
second one contains a semicolon which is a paths separator so it is out,
leaving only `/foo/bar` and `/abc`, in order.
5. The cartesian product of paths from 4. and suffixes from 3. is taken,
giving four variants. In each variant, a `/lua` path segment is inserted
between path and suffix, leaving:
- initial |package.cpath| (defined at compile-time or derived from
`$LUA_CPATH` / `$LUA_INIT`) contains `./?.so;/def/ghi/a?d/j/g.elf;/def/?.so`.
