Meta-annotate @SpringBatchTest with @ExtendWith(SpringExtension.class)

This PR meta-annotates @SpringBatchTest with @ExtendWith(SpringExtension.class) so it can be used in a JUnit Jupiter test without having to extend the test class with SpringExtension.

Issue #3647

@sbrannen Hi Sam,

Could you please take a look at this PR? Let me know if it needs any updates.

Many thanks upfront!

I think the changes look good.

I only made a small suggestion regarding the JavaDoc and pointed out a convenience feature of the Spring TestContext Framework.

As a sanity check, you might want to manually verify that JUnit Jupiter artifacts don't end up as mandatory dependencies in the generated POM.

Thank you for your feedback! I pushed an update that addresses your suggestions. Let me know if anything else should be updated.

I did a quick check, and the dependency is optional as expected, here is an extract from the generated pom:

    <dependency>
      <groupId>org.junit.jupiter</groupId>
      <artifactId>junit-jupiter-api</artifactId>
      <version>5.6.2</version>
      <scope>compile</scope>
      <optional>true</optional>
    </dependency>
