Bug description
The unityLicensingServer input is completely ignored when running on Windows.

How to reproduce

1. setup a job on windows github runner

runs-on: windows-latest

2. add a step with game-ci/unity-test-runner and unityLicensingServer in inputs:

      - name: Test
        uses: game-ci/unity-test-runner@main
        with:
          unityLicensingServer: https://server..
          projectPath: .
          testMode: playmode
          artifactsPath: reports
          checkName: UnitTests Results

3. Run

• Result
  The run fails with

License activation strategy could not be determined.

Visit https://game.ci/docs/github/activation for more
details on how to set up one of the possible activation strategies.
Error: No valid license activation strategy could be determined. Make sure to provide UNITY_EMAIL, UNITY_PASSWORD, and either a UNITY_SERIAL \
or UNITY_LICENSE. See more info at https://game.ci/docs/github/activation
Error: The process 'C:\Windows\system32\docker.exe' failed with exit code 1

• Expected behavior
  The entrypoint script will acquire a new license like it does in Linux:
