Subject: [PATCH] Show proper error when a @QuarkusTest is run from a
 non-Quarkus project dir

This change fixes the (not uncommon) case where the IDE picks the wrong
working directory to launch the tests.
Without this PR, Quarkus throws a totally un-actionable message
regarding SmallRye Config's inability to expand the platform
properties

Fixes: #18132
