PR LGTM, but it fails validation:

Error:  Failed to execute goal net.revelc.code:impsort-maven-plugin:1.7.0:check (default) on project quarkus-test-cli: Imports are not sorted in /home/runner/work/quarkus-test-framework/quarkus-test-framework/quarkus-test-cli/src/main/java/io/quarkus/test/services/quarkus/CliDevModeLocalhostQuarkusApplicationManagedResource.java -> [Help 1]

This needs to be fixed first.

LGTM!
