add_playlist_items adds a different videoId than the one provided

[srajangarg]

Describe the bug
On adding some videoId to a playlist, I notice some other version of the song (with a different videoId) is added instead

To Reproduce
script to illustrate bug

from ytmusicapi import YTMusic
ytmusic = YTMusic("oauth.json")


def get_or_create_playlist_by_name(name: str):
    my_playlists = ytmusic.get_library_playlists(limit=None)
    playlist = next((playlist for playlist in my_playlists if playlist['title'] == name), None)
    
    if playlist is None:
        playlistId = ytmusic.create_playlist(name, description="")
    else:
        playlistId = playlist['playlistId']
    
    playlist_details = ytmusic.get_playlist(playlistId, limit=None)
    return playlist_details

def print_playlist_songs(playlist_name: str):
    playlist = get_or_create_playlist_by_name(playlist_name)
    print(f"Playlist {playlist_name} has {len(playlist['tracks'])} song(s)")
    for song in playlist['tracks']:
        print(song['videoId'])
    print()

def add_song_to_playlist(playlist_name: str, song_id: str):
    print(f"Adding song {song_id} to playlist {playlist_name}\n")
    playlist = get_or_create_playlist_by_name(playlist_name)
    response = ytmusic.add_playlist_items(playlist['id'], [song_id])
    print(f"{response}\n")

# print empty playlist
print_playlist_songs("dummy")

# # add song to playlist and print again
add_song_to_playlist("dummy", "XMNiZfeCmeo")
print_playlist_songs("dummy")

prints
