Fix references to Java client docs (#1071)

In elastic/elasticsearch-java#988 we restructure
the 9.x Java client docs to re-instate the folder structure we had with
asciidoc along with adding docs for new 9.0 features.

Because of this, some references to the Java docs will need to be
updated once that PR is merged. This PR fixes this.

 Schema
 :   When the example code was run an index mapping was created automatically. The field types were selected by {{es}} based on the content seen when the first record was ingested, and updated as new fields appeared in the data. It would be more efficient to specify the fields and field types in advance to optimize performance.

 This happens in particular when the project is using the [Spring Boot Maven Plugin](https://docs.spring.io/spring-boot/docs/current/maven-plugin/reference/htmlsingle/), as this plugin [defines versions for commonly used libraries](https://github.com/spring-projects/spring-boot/blob/main/spring-boot-project/spring-boot-dependencies/build.gradle), including `elasticsearch-rest-client`. Depending on the version of Spring Boot used in the project, that version may be outdated.
