Improve message about map updates

[Kebap]

(mapper): The games map was updated - you should update yours! Go to Settings -> Mapper tab and 
click on the button there. Once you've updated, click here to remove the reminder.

Discord user GamingBuddy commented this:

how do we update the map again? I have always gotten the game map was updated, you should update yours. And everytime I update, I miss a step and keep getting spammed. Till I learnt I need to delete old map first or something before updating. Can someone tell me that extra step? In a new game and it's annoying me I know there are extra steps and I think I fixed it. But maybe a suggestion where it gives clearer instructions? click on the button there isn't very instructive

Maybe "click on the button there." Should read more like maybe "click on the button that says XXX." Where XXX is what exactly?

To be explicit, this is referring the second sentence in above message starting with "Go to". Not the third sentence with the embedded link.
