[Feature Request] Ability to append Java Instance Arguments after the instances own arguments.

[skyant83]

Normally I would append the -Ddiscordfix=" net.minecraft.client.main.Main " to the end of the java launch arguments to allow discord to detect Minecraft as a game.

While I am able to set the Java Arguments Globally or per Instance, I noticed that doing so would cause Minecraft to launch in vanilla. Checking the logs shows that the first line when launching the game is

GDLauncher@N/A: Completely ignored arguments: [", -Dorg.lwjgl.util.Debug=true, cpw.mods.bootstraplauncher.BootstrapLauncher, --launchTarget, forgeclient, --fml.forgeVersion, 43.3.5, --fml.mcVersion, 1.19.2, --fml.forgeGroup, net.minecraftforge, --fml.mcpVersion, 20220805.130853]

After messing around more with the settings, I came to the conclusion that all custom java launch arguments are placed before the necessary arguments for the forge to launch properly.

Request: The ability to choose to add the java arguments after the forge launch arguments
