The new flag "enable-http2" doesn't work for helm plugin. The operator's http connection is still http2 after set the 'enable-http2=false'.    

operator-sdk version: "v1.34.0-10-gc762768c", commit: "c762768c8a128563147dd99218e4ba9ecc035557", kubernetes version: "v1.28.0", go version: "go1.21.4", GOOS: "linux", GOARCH: "amd64"
    

    always

    1.generate one helm type operator
    2.run the operator
    3.port-forward the operator 8443
$oc port-forward nginx-operator-controller-manager-66774759d5-mwp7d 8443:8443
    4. get the tcp message
$curl -vksl https://localhost:8443     

   The tcp contact is still http2 type
