RFR: 8359896: [TestBug][JUnit5] Possible configuration error

[Ambarish Rapte]

A simple change to remove `@Test` annotation from two graphics unit tests.

The two tests have 2 test annotations `@Test` and `@RepeatedTest`, It results in warning message.


WARNING: Possible configuration error: method [public void test.javafx.concurrent.ServiceLifecycleTest.cancelCalledFromOnSucceeded()] resulted in multiple TestDescriptors
[org.junit.jupiter.engine.descriptor.TestMethodTestDescriptor, org.junit.jupiter.engine.descriptor.TestTemplateTestDescriptor].
This is typically the result of annotating a method with multiple competing annotations such as @Test, @RepeatedTest, @ParameterizedTest, @TestFactory, etc.
