ci: nerdctl: Switch to tcp port 80 ping

Browse Source 
TIL that the Azure VMs we use are created without an explicit outbund
connectivity defined.

This leads us to issues using `ping ...` as part of our tests, and when
consulting Jeremi Piotrowski about the issue he pointed me out to two
interesting links:
* https://learn.microsoft.com/en-us/azure/virtual-network/ip-services/default-outbound-access
* https://learn.microsoft.com/en-us/archive/blogs/mast/use-port-pings-instead-of-icmp-to-test-azure-vm-connectivity

For your own sanity, do not read the comments, after all this is
internet. :-)

Anyways, the suggestion is to use nping instead, which is provided by
the nmap package, so we can explicitly switch to using the tcp port 80
for the ping.  With this in mind, I'm switching the image we use for the
test and using one that provided nping as a possible entry point, and
from now on (this part of) the tests should work.

Fixes: #7910
