As we don't have a `RankInfo.F`, this is the next best choice. I am also
adding a check osu-web side for this - this is just to make sure we
aren't sending scores with SS when they are not actually completed.
I'm working on a separate PR to ensure this does not get mutated during
the player exit process.
As discussed in https://github.com/ppy/osu/issues/13864, Squirrel will
use the product name before the title, allowing us to use this variable
to update the icon while not changing the window display title or naming
elsewhere.
