wrapper-provision-jdk plugin not updating Gradle wrapper after Gradle 9 upgrade

### Description

The `wrapper-provision-jdk` plugin appears to be incompatible with Gradle 9. After running the wrapper provisioning task, no changes are applied to the Gradle wrapper script.

### Steps to reproduce

1. Upgrade project to Gradle 9
2. Execute `./gradlew --rerun-tasks clean wrapperProvisionJdk` locally
3. Observe that the build succeeds but no modifications are made to the `gradlew` script

### Expected behaviour

The wrapper provisioning task should update the Gradle wrapper script to include JDK provisioning logic, as it did in Gradle 8.

### Actual behaviour

Build completes successfully with no changes to the wrapper files:
```
BUILD SUCCESSFUL in 4s
3 actionable tasks: 3 executed
```

The `gradlew` script remains unchanged after execution.

### Environment

- Gradle version: 9.1.0
- Plugin: wrapper-provision-jdk
- Execution context: Local machine (not CI/Renovate)

### Additional context

This issue was discovered during local testing after a Gradle version upgrade. The plugin may require updates to maintain compatibility with Gradle 9's wrapper implementation.

We're currently working around this by having devs provision manually.
