Unable to override feature gate argument in capi deployment.

Description

After the major release (1.5 -> 1.6) change in core-components. The position of feature gate arguments is moved up by 1.

https://github.com/kubernetes-sigs/cluster-api/releases/download/v1.6.3/core-components.yaml

Earlier it was

    spec:
      containers:
      - args:
        - --leader-elect
        - --metrics-bind-addr=localhost:8080
        - --feature-gates=MachinePool=${EXP_MACHINE_POOL:=false},ClusterResourceSet=${EXP_CLUSTER_RESOURCE_SET:=false},ClusterTopology=${CLUSTER_TOPOLOGY:=false},RuntimeSDK=${EXP_RUNTIME_SDK:=false},MachineSetPreflightChecks=${EXP_MACHINE_SET_PREFLIGHT_CHECKS:=false}
        command:
        - /manager

Now it is

    spec:
      containers:
      - args:
        - --leader-elect
        - --diagnostics-address=${CAPI_DIAGNOSTICS_ADDRESS:=:8443}
        - --insecure-diagnostics=${CAPI_INSECURE_DIAGNOSTICS:=false}
        - --feature-gates=MachinePool=${EXP_MACHINE_POOL:=false},ClusterResourceSet=${EXP_CLUSTER_RESOURCE_SET:=false},ClusterTopology=${CLUSTER_TOPOLOGY:=false},RuntimeSDK=${EXP_RUNTIME_SDK:=false},MachineSetPreflightChecks=${EXP_MACHINE_SET_PREFLIGHT_CHECKS:=false}

Expected Output

Currently capi deployment looks like

      spec:
        containers:
        - args:
          - --leader-elect
          - --diagnostics-address=:8443
          - --feature-gates=MachinePool=false,ClusterResourceSet=false,ClusterTopology=false
          - --feature-gates=MachinePool=false,ClusterResourceSet=false,ClusterTopology=false,RuntimeSDK=false,MachineSetPreflightChecks=false
          command:
          - /manager

However, It should look like this

spec:
      containers:
      - args:
        - --leader-elect
        - --diagnostics-address=:8443
        - --insecure-diagnostics=false
        - --feature-gates=MachinePool=false,ClusterResourceSet=false,ClusterTopology=false
        command:
        - /manager
