feat(gradle-wrapper): add support for gradle daemon JVM discovery

[Churro]

Changes

Adds support for an incubating Gradle functionality that allows users to configure the JVM used to run a Gradle build. This was first introduced with Gradle 8.8 (see here).

This PR extends the Java constraint evaluation to check if gradle/gradle-daemon-jvm.properties exists and if so, to extract the toolChainVersion property value as the major version to use for the constraint.

Context

• Closes Gradle: Support installation of JDK version requested by Gradle Daemon JVM Discovery #30165

Documentation (please check one with an [x])

• I have updated the documentation, or
• No documentation update is required

How I've tested my work (please select one)

I have verified these changes via:

• Code inspection only, or
• Newly added/modified unit tests, or
• No unit tests but ran on a real repository, or
• Both unit tests + ran on a real repository

Test repo: https://github.com/renovate-demo/30165-gradle-jvm

• Before this PR, running renovate on this repo to update the gradle-wrapper fails with an error:

> "stderr": "\nFAILURE: Build failed with an exception.\n\n* What went wrong:\nCannot find a Java installation on your machine matching the Daemon JVM defined requirements: Compatible with Java 21 (from gradle/gradle-daemon-jvm.properties).\n\n*,

• With this change, the Java 21 constraint is detected:
