docs: newreposetup: Drop section about 'libvirt project server'

Now that most things were migrated out of the old server which hosted
the 'libvirt.org' web (now handles only 'https://download.libvirt.org')
which no longer even hosts the cgit web interface (any link redirects to
gitlab) the whole section now is obsolete. Remove it.
