Unhelpful error message if JDK is too new compared to Gradle

[anthonyvdotbe]

The extension sometimes incorrectly suggests to "upgrade" Gradle, while in fact it would be a downgrade.

Environment

• Operating System: Windows 11
• JDK version: 20
• Visual Studio Code version: 1.82
• Java extension version: v1.22.2023090904

Steps To Reproduce

1. use JDK 20 as the default JDK on your PC
2. open a Gradle project that targets JDK 17 and has a Gradle wrapper at version 7.5

Current Result

The unhelpful error as shown above.

Expected Result

A helpful error, which suggests to either (a) upgrade Gradle to a reasonable version, or (b) configure java.configuration.runtimes to use an actual JDK 17 installation for the JavaSE-17 runtime.
