Native Music app Library subpages sort button needs proper VoiceOver label

1. Enable VoiceOver.
2. Open the Music app and navigate to the Library tab.
3. Go to any of the Library subpages - Playlists, Artists, Albums, Songs, Made For You, or Genres.
4. At the top right is a button used to change the sort order of content on the selected page.

Expected Results:

The sort button should have a clear, concise VoiceOver label such as "Sort" or "Change Sort Order."

Actual Results:

The current VoiceOver label is "line.3.horizontal.decrease" which does not properly convey the purpose of this button.

Impact:

The unclear VoiceOver label for the sort button makes it difficult for VoiceOver users to understand that this button can be used to change the sort order on the Library pages. This results in a poor accessibility experience.

Proposed Fix:

Update the VoiceOver label on the Library page sort button to be more meaningful and accessible such as "Sort" or "Change Sort Order."
