The embedded server used to generate the logging configuration doesn't set a stability level to https://github.com/wildfly/wildfly-plugin-tools/blob/main/src/main/java/org/wildfly/plugin/tools/cli/CLIWrapper.java#L216

This does work when the started server contains only features at community level.

But when a provisioned server contains features at a lower stability level (eg: grpc feature-pack contains preview subsystem), the server fails to start.

A stability level parameter should be provided when calling the BootableJarSupport: https://github.com/wildfly/wildfly-maven-plugin/blob/main/plugin/src/main/java/org/wildfly/plugin/provision/PackageServerMojo.java#L574

experimental should be provided to allow to load a server containing features at all stability levels.

In addition to bootable JAR, CLI script that uses embedded server are also broken.
