README: replace the outdated screenshots

The screenshots showed Proxmox VE 8.4.6 on a light theme, captured in
August 2025, with the old dashboard layout of eight pages named PVE,
Storage, QEMU/KVM-VMs, LXC - Container, Backup, Nodes, Tasks and Network.
The template ships five pages named Overview, Virtual machines, LXC
containers, Storage and disks, and Nodes and HA, so the images no longer
matched what a user gets after the import. Replaced with current captures
of those five pages.

The file is now identical to the README of the upstream repository.
