Java 17 installed by default in hexparrot/mineos docker image

Hello!

Official mineos docker image (latest) still uses Java 16.0.1. This prevents launching 1.18.0 servers that requires Java 17. It is possible to update the Java version by hand but it’s not really user friendly.

Could:

  1. The docker be updated to use OpenSDK 17
  2. It correctly detect that a server couldn’t start because of Java, because right now the start appears as a success in the notifications.

Thanks!
