text: Title: [k8s] Local K8s cluster doesn't work with GPU models containing numbers only.
  Body: I followed the troubleshooting guides to check GPU support: 
  https://docs.skypilot.co/en/latest/reference/kubernetes/kubernetes-troubleshooting.html#checking-gpu-support
  
  - Step B0 - Is your cluster GPU-enabled? ✅
  ```
  llc@LLC:~$ kubectl describe nodes
  Name:               ai-dev
  ...
  Capacity:
    ...
    nvidia.com/gpu:     1
    ...
  ```
  - Step B1 - Can you run a GPU pod? ✅
  ```
  llc@LLC:~$ kubectl logs skygputest

  ```
  
  - Step B2 - Are your nodes labeled correctly? ✅
  ```
  llc@LLC:~$ kubectl get nodes -o json | jq '.items[] | {name: .metadata.name, labels: .metadata.labels}'
  ...
  skypilot.co/accelerator=4090
  ...
  ```
  - Step B3 - Can SkyPilot see your GPUs? ✅
  ```
  llc@LLC:~$ sky show-gpus --cloud k8s
  Kubernetes GPUs (context: default)
  GPU   REQUESTABLE_QTY_PER_NODE  TOTAL_GPUS  TOTAL_FREE_GPUS
  4090  1                         1           1
  
  Kubernetes per node accelerator availability
  NODE_NAME  GPU_NAME  TOTAL_GPUS  FREE_GPUS
  ai-dev     4090      1           1
  ```
  
  - Step B4 - Try launching a dummy GPU task ❌
  ```
  llc@LLC:~$ sky launch -y -c mygpucluster --cloud k8s --gpus 4090:1 -- "nvidia-smi"
  Task from command: nvidia-smi
  No resource satisfying Kubernetes({'4090': 1}) on Kubernetes.
  sky.exceptions.ResourcesUnavailableError: Kubernetes cluster does not contain any instances satisfying the request: 1x Kubernetes({'4090': 1}).
  To fix: relax or change the resource requirements.
  
  Hint: sky show-gpus to list available accelerators.
        sky check to check the enabled clouds.
