Java 13 on glitch

Please add java 13. Java 13 to host lavalink server

It seems like a good idea to me. A lot of people of have been requesting and talking about this because of lavalink.

I also noticed it uses Kotlin and I have no idea if that is supported on Glitch.

I set up GraalVM (a language runtime from Oracle, the owners of Java) on Glitch. You could try remixing my project to set up GraalVM to run your Java code. It’s currently configured to run Node.js.
