World Generation texts aren't updated

The text shown when loading a Minecraft World still says old messages
For example : When loading a world I get the text "Need Diamonds try mining at y11"
But it should be changed to "y -59".

Also,
The seed picker has become useless because the world generation has changed in 1.18 and the seed picker's seeds are of 1.17 so they need to be updated as well.
