CLI app created for latest LTS selects unsupported Gradle version, build fails #49963
Description
Describe the bug
When creating a new Quarkus app using the CLI with options for latest LTS stream 3.20 and Gradle as build tool, the newly created app does not build.
The CLI selects Gradle 9.0.0, which is not supported in Quarkus 3.20.
Expected behavior
The CLI should select a version of the build tool, that is supported by the stream supplied, or should provide the option to override the build tool version.
Actual behavior
CLI creates app with Quarkus version 3.20.2.2 and Gradle wrapper for Gradle 9.0.0.
This combination does not build:
$ ./gradlew build

Welcome to Gradle 9.0.0!
Here are the highlights of this release:
- Configuration Cache is the recommended execution mode
- Gradle requires JVM 17 or higher to run
- Build scripts use Kotlin 2.2 and Groovy 4.0
- Improved Kotlin DSL script compilation avoidance
