[Improvement] clarify docker test failure messages

[mchades]

What would you like to be improved?

Since the default value of skipDockerTests is true.
When user runs the docker tests task without setting skipDockerTests=false, the test will be failed but the error message is confused:

• What went wrong:
  Execution failed for task ':integration-test:test'.

No tests found for given includes: [org.apache.gravitino.integration.test.client.AuditIT](--tests filter)

note: use ./gradlew :integration-test:test --tests "org.apache.gravitino.integration.test.client.AuditIT" to reproduce

How should we improve?

We should add configuration modification instructions in the error message to help users locate the cause of the error more easily.
