[nhh]

When you want to parse annotations or labels or simple lists like [1,2,3,4]

 declare const $env: {
  /** Parses `K8X_MY_TEST=abc` into abc */

   * @example
   * 
   * $env.get("INGRESS_CLASS_ANNOTATIONS")
   * -----------
   * K8X_INGRESS_CLASS_ANNOTATIONS_KEY_1=nginx.ingress.kubernetes.io/app-root
   * K8X_INGRESS_CLASS_ANNOTATIONS_VALUE_1='/var/www/html'
   * -----------
   * K8X_INGRESS_CLASS_ANNOTATIONS_KEY_2=nginx.ingress.kubernetes.io/enable-cors
   * K8X_INGRESS_CLASS_ANNOTATIONS_VALUE_2=true
