Bump Java build requirements to 17, 21 & 25

[sbesson]

Consistently with the Java support roadmap discussed at the weekly OME meeting - https://docs.google.com/spreadsheets/d/1hXjl3WXM5iXHVZbCi4CI-FWF_rcnPOdhlWig48Cub5c/edit?gid=1511932992#gid=1511932992, this PR updates the micro-service to:

• bump the minimal build requirement to Java 17
• keep Java 11 as the minimum runtime requirement
• add Java 25 LTS to the build matrix
• bump Gradle to version 9 - see https://docs.gradle.org/current/userguide/compatibility.html
• add additional metadata to the JAR manifest

Thanks, @sbesson. I was already using a version of this locally since my Eclipse driven workflow as currently Java 25. Will take a closer look at the details but I'm definitely fine with it conceptually.

Might be an idea to loose the Gradle 10 warnings by performing these changes?

Builds nicely for me on 17 (Linux) and 25 (Linux and Windows). Code also still runs nicely on 11 (Linux) built with 25 as well as 17 (Linux) and 25 (Windows).

Looks good. Build fails with java 11, succeeds with the others.

Ran 11, 17, 21, and 25 against a java 25 build successfully (Ubuntu 22.04)
