如何让github action中的作业每天随机运行1到50次？

name: Random Run

on:
  schedule:
    - cron: '0 0 * * *' # 每天午夜触发

jobs:
  random-run:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        run-count: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50]

    steps:
    - name: Checkout repository
      uses: actions/checkout@v2

    - name: Set up random seed
      run: echo "RANDOM_SEED=$(shuf -i 1-50 -n 1)" >> $GITHUB_ENV

    - name: Check if this job should run
      run: |
        if [ $RANDOM_SEED -eq ${{ matrix.run-count }} ]; then
          echo "Running job with seed $RANDOM_SEED"
          # 这里可以添加你的作业步骤
        else
          echo "Skipping job with seed $RANDOM_SEED"
          exit 0
        fi
