Subject: [PATCH] godoc: avoid skipping heading level in package docs

The heading of the #pkg-index section of package documentation pages
uses an h2 heading but its 'Examples' and 'Package files' subsections
use h4 headings, skipping the h3 level.

This change switches the h4s to h3s and adds styling to preserve the
current font-size with the new heading level.

For golang/go#22171
