Describe the bug (required)

The additional information is sometimes used on setlists to provide important information. For example Miku Expo 2024 Europe lists songs played in all locations, but uses additional information to show that some songs only played at specific venues.

This information is not visible on the event / concert pages, leading to user confusion.

To Reproduce (optional)

Steps to reproduce the behavior:

1. Go to https://vocadb.net/L/18446 and observe additional information added to specific songs (eg. London / Amsterdam)
2. Go to https://vocadb.net/E/7266 and observe that the additional information is not there

Expected behavior (optional)

The additional information entered on a setlist should be visible when that setlist is viewed/embedded on a concert page.
