seo: bring meta descriptions into Bing's range, and add IndexNow

Bing Webmaster Tools flags meta descriptions under roughly 90-100
characters. It counts characters, so most Chinese, Japanese and Korean
pages failed even when the text read fine.

- Hand-written descriptions for the key site pages in 11 languages:
  home, pricing, support, team, the blog index and its categories. Plus
  16 docs pages whose text is too short to extend from.
- scripts/fit-meta-descriptions.mjs runs after both builds (v3/build.sh,
  deploy.sh and the docs workflow). It brings every other description to
  120-160 characters, using the page's opening sentences.
- Category descriptions now resolve for the transliterated zh/ja/ko
  slugs. Before, those pages only ever showed the generic text.
- IndexNow: the key file ships with the site from v3/public, and
  scripts/indexnow.mjs submits the live sitemaps. After deploying, each
  workflow submits its own half: the site or the docs.
- Translate the bodies of the Spanish team page and the German support
  page, which were still in English.
