build: initial attempt to fix docs site deployment (#30372)

This fixes a few issues:

- uses the monorepo checked-in docs sources for deployment of >=v19
- properly installs dependencies for that repository, avoiding
  mismatches with the checked-in yarn of the monorepo root.
- avoids sandbox when launching puppeteer for audits

(cherry picked from commit 7c57f82)
