Windows setup fails on beta channel

[derdilla]

A workflow like the one from the example fails on windows:

windows:
  runs-on: windows-latest
  steps:
    - uses: actions/checkout@v4
    - uses: subosito/flutter-action@v2
      with:
        channel: 'beta'
    - run: flutter build windows --release

After downloading the following error is displayed in the log:

flutter/docs/engine/ci/Engine-pre‐submits-and-post‐submits.md:  mismatching "local" filename (flutter/docs/engine/ci/Engine-pre���submits-and-post���submits.md),
         continuing with "central" filename version
