chore: copy ep_products and ep_theme from EP/website@9593cc8

Copied unchanged from public/typo3conf/ext/ of EP/website at
9593cc8631354f8a363d6609de8b7433f669a9a0 (Git-tracked files only).
History stays in the old repository. Only composer.json files are
added so the extensions install as path packages.
