clabverter: failed to add configmap volume when using startup-config inside kinds

[italovalcy]

when using startup-config inside kinds, clabverter fails to add the correspondent configmap to the created deployment:

name: my_lab
topology:
  defaults:
    kind: linux
    image: ghcr.io/srl-labs/alpine
    binds:
      - configs/client.sh:/config.sh
    exec:
      - "ash -c '/config.sh ${NODE_ID}'"
  kinds:
    srl:
      kind: nokia_srlinux
      type: ixrd3
      image: ghcr.io/nokia/srlinux:latest
      startup-config: configs/srl.cfg
  nodes:
    node1:
      kind: srl
    node2:
      kind: nokia_srlinux
      image: ghcr.io/nokia/srlinux:24.10.1
      startup-config: configs/srl.cfg
    host1:
      env:
        NODE_ID: "1"
    host2:
      env:
        NODE_ID: "2"

  links:
    # links between client1 and srl1
    - endpoints: [host1:eth1, node1:e1-1]

    # inter-switch link
    - endpoints: [node1:e1-10, node2:e1-10]

    # links between client2 and srl2
    - endpoints: [node2:e1-1, host2:eth1]

Then, after creating the lab, we see that the container keeps in the CrashLoop state:

> kubectl --kubeconfig $KUBECONFIG -n kubernp get pods -l clabernetes/topologyOwner==clab-0a5adb59405a4e

And looking for more details:

> kubectl --kubeconfig $KUBECONFIG -n kubernp logs clab-0a5adb59405a4e-node1-789c6b8f-4qnv5

...
