Minecraft launcher Debian package depends on default-jre

The debian package for the Minecraft Java Edition launcher depends on the default-jre package, which is unnecessary for two reasons.

1. default-jre is a meta-package which installs openjdk-11-jre. Java 11 is outdated and Minecraft Java Edition needs Java 17.
2. Minecraft Launcher installs Java 17 independently as java-runtime-beta and java-runtime-gamma.

This is also inconvenient for users who wish to choose what version of Java is installed system-wide.
