Activation fails on `windows-2025`

[bitsandfoxes]

Bug description

When targeting windows-latest (which translates to windows-2025 right now) the builds fail with

###########################
#        Activating       #
###########################

Adding licensing server config
Unable to retrieve boot drive serial number
Acquired floating license: "" with timeout 

Targeting windows-2022 succeeds.
Targeting ubuntu-latest succeeds.

How to reproduce

We're running the action as part of CI in this configuration

  build:
    name: Build for ${{ matrix.targetPlatform }}
    runs-on: ${{ matrix.os }}
    strategy:
      fail-fast: false
      matrix:
        include:
          - targetPlatform: StandaloneWindows64
            os: windows-latest
          - targetPlatform: Android
            os: ubuntu-latest

      # ... some other steps 

      - uses: game-ci/unity-builder@v4
        if: steps.cache-build.outputs.cache-hit != 'true'
        with:
          unityVersion: ${{ env.UNITY_VERSION }}
          targetPlatform: ${{ matrix.targetPlatform }}
          unityLicensingServer: ${{ secrets.LICENSE_SERVER_URL }}
          buildName: SentaurSurvivors-${{ matrix.targetPlatform }}
          customParameters: -dsn ${{ secrets.DSN }} -auth_token ${{ secrets.AUTH_TOKEN }} # Arguments cannot be passed via ENV
          allowDirtyBuild: true

      # ... some more steps

Expected behavior

Unity activates and builds the game on all supported platforms.

In order to be able to run on windows-2025, we would need to change the Windows docker images from Windows Server 2022 to Windows Server 2025.

This is a limitation of Windows images from Microsoft: https://learn.microsoft.com/en-us/virtualization/windowscontainers/deploy-containers/version-compatibility?tabs=windows-server-2025%2Cwindows-11#build-number-new-release-of-windows
