fix(checks): correctly check the addresses count in the AVD-NIF-0001 rule

[aokumasan]

The nifcloud computing rules were migrated to Rego at #185, but I found a difference with original Go rule.

Go: https://github.com/aquasecurity/trivy-checks/blob/v1.1.0/checks/cloud/nifcloud/computing/no_public_ingress_sgr.go#L40

if cidr.IsPublic(rule.CIDR.Value()) && cidr.CountAddresses(rule.CIDR.Value()) > 1 {

Rego: https://github.com/aquasecurity/trivy-checks/blob/v1.1.0/checks/cloud/nifcloud/computing/no_public_ingress_sgr.rego#L39

cidr.is_public(rule.cidr.value)
cidr.count_addresses(rule.cidr.value) > 0

In Golang, it was an error if the address count was more than 1 (> 1), But in Rego, it is an error if the count is greater than 0 (> 0).
I think it is correct to follow the Go code and use > 1 as the condition.
