Upgrade nginx-ingress to version v1.0.0 or higher, to support for Kubernetes 1.22

Summary

Upgrade nginx-ingress to version v1.0.0 or higher, due to support for Kubernetes 1.22 https://kubernetes.io/blog/2021/07/26/update-with-ingress-nginx/

Steps to reproduce

• Install a Kubernetes cluster running Kubernetes 1.22 (available August, 2021)
• Install the Gitlab chart onto that cluster with our ingress-nginx enabled
• Note that ingress-nginx fails to install and run correctly due to removed APIs

Current behavior

ingress-nginx fails to install correctly so Gitlab installed via helm not accessable

Expected behavior

ingress-nginx installs correctly so Gitlab installed via helm is accessable
