### Problem Description

Importing Playlists from YT is not possible. Now that Local Playlist support has released we can start to implement this.

### Proposed Solution

The ability to import the Playlist file provided by YouTube into FreeTube

Also what we need from the exported YT playlist file to test cases like:

- videos that are set to private in that playlist
- videos that dont exist anymore
- shorts and previously streamed live videos
- Currently live videos (not sure if YT allows u to save that to a playlist)
- Upcoming videos or upcoming live videos (not sure if YT allows u to save that to a playlist)

### Alternatives Considered

None.

### Issue Labels

new feature
