text: Title: Fix the NPM_FILE_PATTERNS setting to work on windows
  Body: Instead of hardcoding the "/" to the entries `NPM_FILE_PATTERNS` you need to use `os.path.join`, as per: https://github.com/kevin1024/django-npm/issues/15
  
  For example:
  
  ```
  NPM_FILE_PATTERNS = {
      "a17t": [os.path.join("dist", "a17t.css"), os.path.join("dist", "tailwind.css")],
      "apexcharts": [os.path.join("dist", "apexcharts.min.js")],
      "litepicker": [os.path.join("dist", "js", "main.js")],
      "turbolinks": [os.path.join("dist", "turbolinks.js")],
      "stimulus": [os.path.join("dist", "stimulus.umd.js")],
      "inter-ui": [os.path.join("Inter (web)", "*")],
      "@fortawesome": [os.path.join("fontawesome-free", "js", "all.min.js")],
  }
  ```
  
  TIA
