secgroups: default: remove port ranges and fix protocol
This port range is reported by the openstack API, the openstack provider as this:
~ port_range_max = 0 -> 65535 # forces replacement
~ port_range_min = 0 -> 1 # forces replacement
Meaning there is a change every tofu apply. Instead, don't set the ports at all.
While at it, fix the icmp protocol string (must be lower case).
