Run Gradle release candidate tests with JDK 17 (#690)

### Issue
Since Gradle 9, JDK 17 is the minimal version to run Gradle
([ref](https://gradle.org/whats-new/gradle-9/#java-17-is-the-minimum-version-to-run-gradle))
Some of the GH workflows in this repository are failing
([example](https://github.com/gradle/actions/actions/runs/16417315636/job/46386404481#step:9:35))
when running against the release candidate (being Gradle 9)

### Fix
Create a dedicated provision-gradle job with JDK 17 instead of the
default 11.
This change is a minimalistic way to fix the issue.
