tauri-plugin-dialog return wrong path

### Describe the bug

eg
When using `tauri-plugin-dialog` on Android mobile devices, after selecting a file through the file picker, the obtained path starts with `content://` instead of returning an absolute file path. This causes subsequent file operations using `tauri-plugin-fs` APIs to fail with "no file" errors. The same code works correctly on desktop platforms.

zh
我认为他是一个bug，tauri-plugin-dialog 在pc上工作良好，但是在移动端例如安卓，选择的文件后获取的路径是以content开头的路径，而没有返回绝对路径，导致我使用其他的tauri-plugin-fs的api显示no file
