Update ruins notification to show exact amount of culture

[SpacedOutChicken]

Now that the ruins reward granting culture adjusts to game speed, it no longer necessarily grants 20 culture. This PR changes the notification to reflect this fact.

This won't work, since we don't inject the amount into the notification... And starting to inject trigger data into the notification sounds like a nightmare
Our options are to either roll back this change, OR to have "+20 culture" be incorrect in some speeds, OR to delete the amount of culture in the notification entirely

I know that in my own Deciv 2 mod, I have a notification that uses [cultureAmount] Culture in it, and it seems to be working. The ruins grants a variable amount of culture ([20]-[30]) and the notification appears to be providing the exact amount of culture being granted. Is something else going on with the notification that Deciv is using? Like I said, it seems to be working for that mod. You can see it here: https://github.com/SpacedOutChicken/Deciv-2/blob/main/jsons/Ruins.json

You're right, we do have a provision for similar changes, I forgot
So it won't be a huge change, but will be a change, since it's unique specific IIRC
