Match Spring SDK config across docs

[akeller]

• Spring SDK: https://docs.camunda.io/docs/apis-tools/spring-zeebe-sdk/getting-started/#self-managed
• Getting started: https://docs.camunda.io/docs/guides/getting-started-java-spring/#configure-the-zeebe-client

Guides should be reviewed and configuration should be aligned (possibly even moved into a partial for reuse).

Is this not resolved by #4439?

[akeller]

It gets us closer. They both use application.yml instead of application.properties now, but the yml is slightly different, and it might be unclear to someone getting started. One solution might be to link https://docs.camunda.io/docs/guides/getting-started-java-spring to catch the fresh beginner audience and assume more advanced users would understand the differences.

@jonathanlukas, wdyt? Were you just looking for application.yml or additional changes?

[jonathanlukas]

yaml format is cool, but I was actually looking for having only one configuration pattern to prevent confusion.
