Updated v20.1 Spring-JPA tutorial to use CRDB Hibernate dialect

[ericharmeling]

Fixes #5992.

• Updated properties file to specify v20.1 CRDB Hibernate dialect.
• Added latest Hibernate version to pom.xml file (Spring Data JPA uses older version that doesn't support CRDB dialect.
• Updated app output.

Before merging this, I need to merge the change to the roach-data repo: cockroachlabs/roach-data#4.

v20.1/build-a-spring-app-with-cockroachdb-jpa.md, line 88 at r1 (raw file):

The [Hibernate CockroachDB dialect](https://in.relation.to/2020/07/27/hibernate-orm-5419-final-release/) is supported in Hibernate v5.4.19+. At the time of writing this tutorial, Spring Data JPA used Hibernate v5.4.15 as its default JPA provider. To specify a different version of Hibernate than the default, add an additional entry to your application's `pom.xml` file, as shown in [the `roach-data` GitHub repo](https://github.com/cockroachlabs/roach-data/blob/master/roach-data-jpa/pom.xml):

This code block renders weird because it's in the callout. Though not ideal, maybe you can preface the note and code block with a "Note:" or "It should be noted that the Hibernate..."
