io.quarkus.grpc.cli.GrpcCliTest.testCommand fails CI and makes it next to impossible to get green CI

Description

I am experiencing in this PR #42749 that after several runs I can't get green CI because of this test. According to the build scan history https://ge.quarkus.io/scans/tests?search.timeZoneId=Europe%2FPrague&tests.container=io.quarkus.grpc.cli.GrpcCliTest&tests.test=testCommand it is not just my PR. For example I found same failure in #42700 from @gsmet. I believe we need to disable this test with link to this issue so that the issue is not forgotten, but also, other PRs are not blocked.

Example stacktrace:

java.lang.RuntimeException: 
java.lang.RuntimeException: io.quarkus.builder.BuildException: Build failure: Build failed due to errors
	[error]: Build step io.quarkus.vertx.http.deployment.VertxHttpProcessor#cors threw an exception: java.lang.IllegalStateException: java.lang.RuntimeException: java.lang.reflect.InvocationTargetException

Implementation ideas

1. Disable the test Disable GrpcCliTest#testCommand due to CI failures #42820
2. Fix the test.

Yeah, this just won't go away ... and the problem is probably not the test, it's something more general ... @gsmet should know more.
