更新templates/NOTES.txt, charts/gitlab/charts/unicorn/templates/ingress.yaml

The previous chart does not support access via http on the intranet, because unicorn insress will use the self-signed certificate, so the cloud native gitlab can not use gitlab and gitlab-runner in the internal network, I can achieve by modifying the unicorn ingress configuration file , Can be accessed on the external network, this is the reason for my merge request
