[BUG] Load test fails on Windows runner

[jcantosz]

Describe the bug
Load test cannot find the JMX file referenced by my config.yml on Windows runners. Works as expected on Linux runners. On Windows it fails with the message: Error: File not found loadtest\quick_test.jmx.

I need to use Windows for my self-hosted runners, so I would like this to work on Windows.

To Reproduce
Steps to reproduce the behavior:

1. Create a load-test actions workflow
2. Set the runs-on: to windows-2019
3. Run the worklfow
4. See error Error: File not found loadtest\quick_test.jmx

name: Azure Load Test

          loadTestResource: 'jcantosz-load-test'
          resourceGroup: 'jcantosz'

  # This job fails

    runs-on: windows-2019
    steps:
      - name: Checkout
        uses: actions/checkout@v3
      - name: 'Az CLI login'
        uses: azure/login@v1
        with:

          tenant-id: ${{ secrets.AZ_TENANT_ID }}
          subscription-id: ${{ secrets.AZ_SUBSCRIPTION_ID }}
      - name: 'Azure Load Testing'
        uses: azure/load-testing@v1
        with:
          loadTestConfigFile: 'loadtest/config.yaml'
          loadTestResource: 'jcantosz-load-test'
          resourceGroup: 'jcantosz'

Expected behavior
I expect the load test to run on Windows the same way it does on Linux
