Subject: [PATCH] Fix storyboard background replacement logic not working for
 beatmaps with multiple backgrounds

In the case where the background image of individual difficulties is
different, querying the beatmap *set*'s metadata as we were will cause
issues.

I haven't added test coverage for this but can if required. Can be
manually tested using https://osu.ppy.sh/beatmapsets/1595773#osu/3377474
(specifically the highest difficulty).

Closes https://github.com/ppy/osu/discussions/16873.
