File extension lost

[fm-sys]

Library version: 1.5.6
OS version: Android 14
Device model: Pixel 7a

Describe the bug
Hi, I have an issue with your library. The file extension is lost when creating a file in the Downloads folder.

Do you know a workaround for it?

To Reproduce

All this doesn't work...

FileDescription description = new FileDescription("test.gpx", "", "");
DocumentFileCompat.createDownloadWithMediaStoreFallback(getApplicationContext(), description);

FileDescription description = new FileDescription("test.gpx", "", null);
DocumentFileCompat.createDownloadWithMediaStoreFallback(getApplicationContext(), description);

FileDescription description = new FileDescription("test.gpx", "", "application/gpx+xml");
DocumentFileCompat.createDownloadWithMediaStoreFallback(getApplicationContext(), description);

---

however, this does work:

FileDescription description = new FileDescription("test.png", "", "image/png");
DocumentFileCompat.createDownloadWithMediaStoreFallback(getApplicationContext(), description);

Does this only happen on Android 14?

At least Android 13 is affected as well, didn't have checked other versions until now though.
