Updated papi.d.ts with new Uri scheme documentation that I missed before

    * Represents a path in file system or other. Has a scheme followed by :// followed by a relative
    * path. If no scheme is provided, the app scheme is used. Available schemes are as follows:
    *
-   * - `app://` - goes to the app's home directory and into `.platform.bible` (platform-dependent)
+   * - `app://` - goes to the `.platform.bible` directory inside the user's home directory.
+   *
+   *   - On Linux and Mac, this is `$HOME/.platform.bible`
+   *   - On Windows, this is `%USERPROFILE%/.platform.bible`
+   *   - Note: In development, `app://` always goes to `paranext-core/dev-appdata`
    * - `cache://` - goes to the app's temporary file cache at `app://cache`
    * - `data://` - goes to the app's data storage location at `app://data`
-   * - `resources://` - goes to the resources directory installed in the app
-   * - `file://` - an absolute file path from root
+   * - `resources://` - goes to the `resources` directory inside the install directory
+   *
+   *   - Note: In development, `resources://` always goes to the repo root, `paranext-core`. Not all files
+   *       are copied into the production `resources` folder, though. See `electron-builder.json5`'s
+   *       `extraResources` for some that are copied.
+   * - `file://` - an absolute file path from drive root
+   *
+   * Note: projects are stored in the production version of `app://projects` regardless of whether you
+   * are in production or development
