Add Open Graph image + Twitter card to every docs page

When a docs.godotengine.org link is shared on X/Twitter, Slack, Discord, LinkedIn or any social platform, the preview currently renders without an image — the site has og:title/og:description (from sphinxext-opengraph) but no og:image and no twitter:card. Each share shows a bare text link instead of a branded card.

What's included

• _static/og-image.png — a 1200×630 social preview image matching the Godot brand: dark navy ground, blue accent bar, section pills (Getting started / Step-by-step / Tutorials / Class reference / Community) and docs.godotengine.org chip. Generated by tools/make-og-image.py (Pillow-only, reproducible).
• conf.py — sets ogp_image/ogp_image_alt so the extension emits og:image on every page, plus ogp_custom_meta_tags for an explicit summary_large_image Twitter card. No explicit twitter:image is set, so Twitter falls back to the version-aware og:image (works for stable, latest, and every 4.x branch).

Verification

Built locally with Sphinx 8.1.3 + sphinxext-opengraph 0.13.0 (pinned versions). Confirmed on the built site:

<meta property="og:image" content="https://docs.godotengine.org/en/stable/_static/og-image.png" />
<meta property="og:image:alt" content="Godot Engine documentation" />
<meta name="twitter:card" content="summary_large_image" />

Per-page og:title/og:description continue to be emitted as before.
