Cannot define a different default jnlp container

      Description

      It seems I cannot define a default jnlp container to be used for all the pods and the plugin defaults always to "jenkins/inbound-agent:4.3-4".

      I specified a custom image in the kubernetes configure clouds page, but the template has always no container and not even the custom ENV var that I specify.

      The workaround I found, is to specify the jnlp in the yaml variable, but i'd prefer to have a global one.

      Here the code:

       node("worker") {
          String yaml = """
      kind: Pod
      apiVersion: v1
      spec:
        containers:
          - name: bash
            image: registry.example.com/registry/shell:bash5.0-alpine3.12
            imagePullPolicy: Always
            command: ["cat"]
            tty: true
          """  podTemplate(yaml: yaml) {
          node(POD_LABEL) {
              stage("Build for packaging") {
                container('bash') {
                  sh label: "Build for packaging", script: """
      set -e
      echo "Test"
      """
                }
              }
          }
        }
      }
      

      Here the logs:
