Subject: [PATCH] Fix NPM API health issues on Debian 13 with certbot-dns-multi

On Debian 13 Trixie, NPM shows 'API isn't healthy' after upgrade.
Install certbot-dns-multi with golang dependencies to fix this.

Changes:
- Install golang, build-essential, git on Debian 13
- Install setuptools-golang==2.9.0 in certbot venv
- Set CGO_ENABLED=1 and GO111MODULE=on for pip install
- Install certbot-dns-multi with --no-build-isolation flag
- Applied to both fresh install and update_script()
