Modulémon 1.2 re-release (without OSGi)

This release is functionality identical to https://github.com/JonasKaad/SemesterProject-4/releases/tag/v1.2 (apart from the changes to the title-screen)
The only difference being that it runs without OSGi, which also means bundles can't be enabled or disabled during gameplay.

This release also ports Modulémon to Java version 18.

You can easier run modulemon-1.2-no-osgi.jar directly using Java 18. Or you may use modulemon-1.2-windows_x64.zip or modulemon-1.2-linux_x64.zip which are both shipped with a Java runtime so can run without dependencies.
The linux build has only been tested on WSL, but as it works there, it is assumed that it also works natively.
