fix(gen_help_html): first tag in h2 is broken #30720

Problem:
In h2 headings, the first tag points to an invalid anchor. This used to
work but regressed a few months ago, possibly related to
ceea6898a8bdcb6c4cfe06b8dc4739c144e6b1f8.

Solution:
- Simplify the logic, don't try to be clever:
  - Always use to_heading_tag() for the h2 `id`.
- Also:
  - Render tags as `<span>`, because `<code>` is unnecessary and doesn't
    look great in headings.
  - In the main h1, use "foo.txt" as the anchor `name` (rarely used),
    prefer the next found tag for the `href`.
