Add an API action to rename an existing internal playlist by ID or name

Feature description

add a rename_playlist custom action to the API that takes a playlist ID and a new name

Problem solved

internal playlists can only be renamed from inside the app. there’s no way to do it externally via automation apps like macrodroid or tasker, especially i have music get added to sub folders which i rename via a script automatically and would like to remame the playlist somehow too through its api if implemented.

Brought benefits

lets users rename playlists through automation without opening symfonium. consistent with how other custom actions like generate_playlist_thumbnail already work using the same playlist ID

Other application solutions

m3u playlist files can be renamed via a file manager since the filename is the playlist name, but internal playlists have no equivalent workaround
