"Duplicate of MC-297" / "Duplicate of MC-128302" RAM recommendation is outdated

The messages "Duplicate of MC-297" and "Duplicate of MC-128302" currently suggest:

Line 338 in 033fa40

    
                   -- If you are using Java arguments to increase the amount of memory, please reduce it to the default 512MB.

Line 323 in 033fa40

    
                   -- If you are using Java arguments to increase the amount of memory, please reduce it to the default 512MB.

However, at least for me the default is actually -Xmx2G (and not 512M). In case this is not a dynamic value depending on the available RAM, it would probably be good to update these messages. Or does someone have a different default value there?

Additionally "Minecraft: Java Edition system requirements" says that at least 4GB of RAM is required, so a maximum of 2GB for the game sounds reasonable.
