For example, this action:

#Note: This is a third party action and currently only supports Linux: https://github.com/marketplace/actions/create-zip-file
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - # 'Note: This is a third party action and currently only supports Linux: https://github.com/marketplace/actions/create-zip-file'
      uses: montudor/action-zip@v0.1.0
      with:
        args: zip -qq -r  ${{ github.workspace }}

Would become:

#Note: (Line 7) This is a third party action and currently only supports Linux: https://github.com/marketplace/actions/create-zip-file
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - # 'Note: This is a third party action and currently only supports Linux: https://github.com/marketplace/actions/create-zip-file'
      uses: montudor/action-zip@v0.1.0
      with:
        args: zip -qq -r  ${{ github.workspace }}
