[Bug]: Can't pass `JAVA_HOME` to the snap to use a different Java version

[NatoBoram]

What happened?

JAVA_HOME="/usr/lib/jvm/java-18-openjdk-amd64" gradle wrapper

* What went wrong:
An exception occurred applying plugin request [id: 'fabric-loom', version: '0.11-SNAPSHOT']
> Failed to apply plugin 'fabric-loom'.
   > You are using an outdated version of Java (16). Java 17 or higher is required.
     The JAVA_HOME environment variable is currently set to (/snap/gradle/134/usr/lib/jvm/java-1.16.0-openjdk-amd64).

What should have happened?

The supplied JAVA_HOME should've been used instead of the built-in one.
