No route to host since macos-15-intel with `colima-network-address: true` set

A recent change seems to break the `colima-network-address: true` usage.

The VM does start, the `colima list` says the VM have an IP, but we can't reach it from host. Constantly getting "No route to host".

Worked perfectly fine with:

- macos-12 (now deleted)
- macos-13 (pending deletion on December)
- macos-14-large (but costly... can't use it much)

stopped working with `macos-15-intel`.

I am completely clueless on why such silent failure would occurs and I have difficulties on getting my hand on a MacOS instance.

Tried to completely disable the firewall but no luck on that side.

regards,

Begin with the action's handling of the `colima-network-address: true` option and reproduce the workflow on a `macos-15-intel` runner, comparing it with macos-12, macos-13, and macos-14 behavior. Confirm completion when the started VM's advertised IP is reachable from the host without “No route to host”.
