fix(v2): Topic Map dimensions must be h2 not h3 (MD001 lint failure)

The Topic Map page H1 is 'Topic Map', so dimension headings jumped h1->h3
and tripped markdownlint MD001/heading-increment, failing 07.2 Markdown
Linter on develop and master after v2.9.16. Emit dimensions as h2 in the
generator, the committed page, and update the CSS selector
(.topic-map-dim h2). Verified 0 errors with the CI markdownlint config.
Bumped v2_elite.css?v=2.9.17.
