fix(fs): fix crash on getting file descriptor from android content uri

[aiueo13]

Fixes a crash that occurs when opening a file from an Android Content URI due to missing permissions or the file not existing.

Details

Before the fix, Kotlin’s getFileDescriptor function would return null when the file was unavailable.

plugins-workspace/plugins/fs/android/src/main/java/FsPlugin.kt

Lines 63 to 67 in 69a9d57

	val fd = activity.contentResolver.openAssetFileDescriptor(
	Uri.parse(args.uri),
	args.mode
	)?.parcelFileDescriptor?.detachFd()
	res.put("fd", fd)

However, on the Rust side that receives it, null triggers unimplemented!(), causing a panic.

plugins-workspace/plugins/fs/src/mobile.rs

Lines 86 to 93 in 69a9d57

	if let Some(fd) = result.fd {
	Ok(unsafe {
	use std::os::fd::FromRawFd;
	std::fs::File::from_raw_fd(fd)
	})
	} else {
	unimplemented!()
	}

And with this PR, the getFileDescriptor function will throw an error instead of returning null when the file is not available.
