Update CRN distrib pages, auto-fetch latest versions, minor fix

[philogicae]

Changes

• Add deprecation page for Debian 11
• Add missing page for Ubuntu 24.04 Noble Numbat
• Minor fix: broken link on metrics page
• During installation, Auto-fetch latest CRN version from github, so we don't have to update pages after each new release anymore:

# Before
wget -P /opt https://github.com/aleph-im/aleph-vm/releases/download/0.4.1/aleph-vm.debian-12.deb
# Now
curl -s https://api.github.com/repos/aleph-im/aleph-vm/releases/latest | grep "browser_download_url.*deb" | cut -d : -f 2,3 | tr -d \" | sed '1p;d' | xargs wget -P /opt -
