Aikar's Flags don't match the Start Script Generator

[Darwin1546]

There is a section in https://docs.papermc.io/paper/aikars-flags, that says if you has 12G+ memory, you should adjust flags a little.

Script Generator completely skips that part and just pastes static flags.

I'll change it to an issue about the Aikar's flags themselves, not the generator based on this and leave it for @olijeffers0n to decide.
Thanks for the report nonetheless.
