java 17 only extensions fails quarkus create app on java 11

[maxandersen]

Describe the bug

since neo4j latest update (quarkiverse/quarkus-neo4j@dd0f7f1) that targets java 17 quarkus create app -x neo4j (with or without --java 11) fails to build.

[ERROR] Failed to execute goal io.quarkus.platform:quarkus-maven-plugin:2.15.3.Final:build (default) on project code-with-quarkus: Failed to build quarkus application: io.quarkus.builder.BuildException: Build failure: Build failed due to errors

Question is how we deal with this since neo4j does have a quarkus-neo4j 1.x version available that works with Java 11.

Feels like we at least could warn or error on it not being possible to use java 11

It would be interesting if extensions could provide the minimum Java info in the extension metadata:

• Introduce minimum-java-version and recommended-java-version #30290

This is now out of date as we use Java 17 as the baseline
