Add Java Version 16 to support upcoming releases

[UNOPARATOR]

I'm running a local papermc server and this warning started to show up lately:

---

• WARNING - YOU ARE RUNNING AN OUTDATED VERSION OF JAVA.
• PAPER WILL STOP BEING COMPATIBLE WITH THIS VERSION OF
• JAVA WHEN MINECRAFT 1.17 IS RELEASED.
• Please update the version of Java you use to run Paper
• to at least Java 16. When Paper for Minecraft 1.17 is
• released support for versions of Java before 16 will
• be dropped.
• Current Java version: 11.0.10
• Check this forum post for more information:
• https://papermc.io/java16

If you would add Java version 16 to list of options, it would be great.

Which would also require changing the available environment variables from

-e JAVA_VERSION=<8|11>

to

-e JAVA_VERSION=<8|11|16>

amongst other things of course.

ok cool, i am awaiting an upstream version bump before this can happen, but it shouldn't be too much work, fyi here is the link:- https://archlinux.org/packages/extra/x86_64/jdk-openjdk/

added java 16, had to go with AUR package for now as AOR has not been updated, image is currently building.

Thanks for the update, the new image is working fine with the JAVA_VERSION=16 settings.
