Add custom message in the case of a invalid beatmap_hash

[64ArthurAraujo]

Closes #27781, very small PR just adding a case for the "invalid beatmap_hash" exception.Message. Now it will show
a better message: "A new version of this beatmapset is available please update. Your score will not be submitted."

[SupDos]

You're missing a comma: available, please

Personally I think a better message for this would be
This beatmap doesn't match the official version, please update or re-download this beatmap.\n\n{whatWillHappen}

This message doesn't necessarily mean that an update to the beatmap is available. It might also mean that the beatmap has been modified (i.e. by changing it in stable and importing from there). Or it might mean that the beatmap was intentionally maliciously modified. Or it might mean corruption. And so on and so forth.

I'm not sure how to feel about this change in that light.

What about the message @SupDos suggested? "This beatmap doesn't match the official version, please update or re-download this beatmap. Your score will not be submitted" it is more generic, i think it fits better
