test: fix vswitch subnets ip_range (#359)

##### SUMMARY

The vswitch subnet validation changed: the subnet ip_range must be
smaller than the network ip_range **AND** must not start with the same
IP.
 
See
https://github.com/ansible-collections/hetzner.hcloud/runs/17672011247

In addition, I reworked the tests to use the new testing framework.
