NGINX: disable or update outdated version drift check

Summary

From gitlab-org/cloud-native/charts/gitlab-ingress-nginx!1 (comment 1018250908)

Interestingly, the code that validates the controller tag is a bit out of date. It's ensuring that the controller is no more than 3 minor versions behind, but the value hasn't been updated since the original PR in 2020.

The shortest path is to remove this outdated drift check, or at least update it.

Acceptance
