New review comment by Skirmisher on void-packages repository

https://github.com/void-linux/void-packages/pull/30089#discussion_r610306368

Comment:
This is referenced in all the associated documentation for the game, so I don't know if a Void-specific README makes sense. The message is intended for users who do a drive-by installation after searching the Void repos without looking up the game separately; if we had an "extended description" field, I would have added it there instead. I would like to get rid of the other section of the message though, that really should be a vpkg or something.

I don't have a strong feeling about the added message though, so if you think it would be better off without, I'd be fine removing it.
