What is the current behavior?
The start-scripts which ServerPackCreator generates are incompatible with Forge versions for Minecraft 1.17.1.
Forge changed the way their server is started with said version, thus requiring a different setup.
If the current behavior is a bug, please provide the steps to reproduce

Generate a Minecraft 1.17.1 Forge server pack and let ServerPackCreator generate start-scripts.
Try to start the server with said start-scripts.

What is the expected behavior?

The scripts generated by ServerPackCreator should work for Minecraft 1.17.1 Forge.

Other information (e.g. detailed explanation, stacktraces, related issues, suggestions how to fix, links for us to have context, eg. stackoverflow, gitter, etc)

A fix will be rolled out together with the changes from #81

Linux:
java @libraries/net/minecraftforge/forge/1.17.1-37.0.82/unix_args.txt

Windows:
java @libraries/net/minecraftforge/forge/1.17.1-37.0.82/win_args.txt
Java 16 is also required for this startup.
Forge 1.17 doesn't have a single jar file like forge 1.16 and lower, so you can't do -jar forge.jar, you have to run unix_args.txt or win_args.txt.

Start scripts generated for Mincraft 1.17+ Forge servers will look almost identical to the regular scripts generated by ServerPackCreator, except some file checks will look for and download files to slightly different locations, as well as the command which finally starts the server being different.

Forge server JAR, for example, is now located at libraries/net/minecraftforge/forge/$MINECRAFT-$FORGE/forge-$MINECRAFT-$FORGE-server.jar

Minecraft server JAR is now located at libraries/net/minecraft/server/$MINECRAFT/server-$MINECRAFT.jar

With $MINECRAFT and $FORGE representing the versions specified by the user generating the server pack.
