MTLS_Port environment variable is generated twice in Deployment Yaml

[lefkatis]

When you use the helm chart to template or install the helm release of akv2k8s you can see that MTLS_PORT and MTLS_PORT_EXTERNAL are generated twice

This causes problems with helm as it shows an error saying:
##[error]W0315 13:22:15.063845 27755 warnings.go:70] spec.template.spec.containers[0].env[5].name: duplicate name "MTLS_PORT"

Helm command used:
helm template --namespace akv2k8s akv2k8s spv-charts/akv2k8s --version 2.1.0

Helm version used: 3.8.1
