Add AI observability wizard command to start here and installation docs

[marco-g-pm]

Changes

The wizard CLI now ships a dedicated ai-observability command ("Add PostHog AI Observability to your LLM calls" — verified against npx @posthog/wizard@latest --help), so this surfaces it in the docs the same way other products do:

• /docs/ai-observability/installation – adds the standard "AI wizard" section at the top with <WizardCommand command="ai-observability" />, followed by a "Platforms" heading around the existing platform grid. Mirrors the error tracking / experiments / surveys installation pages.
• /docs/ai-observability/start-here – the first quest step now offers the wizard as the fastest install path (same flow as MCP Analytics and Product Analytics start-here pages), keeping the platform grid as the manual option.
• /docs/ai-engineering/ai-wizard – adds the wizard ai-observability row to the commands table.
• src/hooks/productData/ai_observability.tsx – flips wizardSupport from 'Coming soon' to true, which moves AI Observability into the supported-products list on the AI wizard page.
• src/navs/index.js – fixes the "AI Observability ↗ ↗" double arrow in the AI engineering docs nav: the label had a literal ↗ baked in and the URL was absolute, so the nav also appended its own external-link icon. Now a clean label with a relative URL, consistent with every other docs entry.

All pages verified locally in a dev server (installation, start-here, and ai-wizard render the command and table row correctly; the nav shows a single clean link).

Checklist

• I've read the docs and/or content style guides.
• Words are spelled using American English
• Use relative URLs for internal links
• I've checked the pages added or changed in the Vercel preview build
• If I moved a page, I added a redirect in vercel.json (no pages moved)

Eager-graph budgets are report-only until a baseline is established. Sizes are gzip of public/**/*.js; eager size is webpack module source bytes for the modules actually shipped in the entrypoint's initial chunks (post-tree-shake).
