Cannot import NewPipe subscriptions. JSON file is filtered in file picker call.

Description

Cannot import NewPipe subscriptions. I exported newpipe-subscriptions.json from LibreTube on Android, but cannot import the file in Pipeline.

The file picker opens, but a filter is applied that prevents me from selecting the file, and cannot be changed to 'All Files' in either the new GNOME 47 Nautilus picker nor the old GTK one.

The filter's MIME type says it wants text/json, but my exported JSON file is never picked up. Not sure what the exact MIME type should be, but also consider allowing 'All Files' to be selectable in the file chooser portal call.
