docs: update og-image wordings to match current site copy

Kicker now mirrors the hero kicker ("The definitive list that
answers..."), replacing the old "field guide" line changed in
8b14b4f. Subtitle now matches the current tagline ("An opinionated
guide to the best Python frameworks, libraries, and tools.") on one
line. PNG regenerated from the SVG.
