Get Started button previously linked to /docs (root), landing users on
Overview. Issue #3848 reporter and concurrent PR #3948 asked for a
deeper link straight to Installation.
lib/docs-sections.ts declares 'installation' as a stable section id
rendered via <section id={section.id}> in app/[locale]/docs/page.tsx,
so /docs#installation is a valid deep link.
This also supersedes the in-flight PR #3948 (which targets the
pre-decomposition landing-page.tsx).
