Nginx Ingress Controller retired as of March 2026

### What would you like to share? The documentation indicates that prospective users of this tool should install the nginx ingress controller. The nginx ingress controller is deprecated and will be fully unmaintained starting in March of this year. Using this ingress controller will result in security vulnerabilities moving forward since it will no longer be receiving any updates. GatewayAPI should be used instead, as this is the recommended path from the Kubernetes SIG discussions about this issue. ### Additional information _No response_
