/**
 * Generate a `DarwinDocumentType` given a list of file extensions, an icon name, and an optional suffix or file type name.
 * @param extensions A list of file extensions, such as `['bat', 'cmd']`
 * @param icon A sentence-cased file type name that matches the lowercase name of a darwin icon resource.
 * For example, `'HTML'` instead of `'html'`, or `'Java'` instead of `'java'`.
 * This parameter is lowercased before it is used to reference an icon file.
 * @param nameOrSuffix An optional suffix or a string to use as the file type. If a suffix is provided,
 * it is used with the icon parameter to generate a file type string. If nothing is provided,
 * `'document'` is used with the icon parameter to generate file type string.
 *
 * For example, if you call `darwinBundleDocumentType(..., 'HTML')`, the resulting file type is `"HTML document"`,
 * and the `'html'` darwin icon is used.
 *
 * If you call `darwinBundleDocumentType(..., 'Javascript', 'file')`, the resulting file type is `"Javascript file"`.
 * and the `'javascript'` darwin icon is used.
 *
 * If you call `darwinBundleDocumentType(..., 'bat', 'Windows command script')`, the file type is `"Windows command script"`,
 * and the `'bat'` darwin icon is used.
