Update Gradle to 9.3.0 and Maven to 3.9.12

bestbeforetoday · bestbeforetoday · commit b32531c195e5 · 2026-01-21T12:54:37.000Z
This change updates both the Gradle wrapper used for the build, and also
the Gradle version bundled in the fabric-javaenv Docker image. Maven is
also updated to 3.9.12 within the Docker image.

Several dependency versions are also updated.
