Remove PROXMOX 5.x / 6.x subscription message popup

# Edits the proxmox Subscription file to make it
# think that it has a Subscription.
#
# Will disable the annoying login message about
# missing subscription.
#
# Tested on Proxmox PVE v5.2-1 and v6.0-4 
#
# The sed command will create a backup of the changed file.
# There is no guarantee that this will work for future versions.
# Use at your own risk!
