SpringBoot Upgrade to Elasticsearch Client 8.15.3

Supersedes #42649

Comment From: christophstrobl

It seems the elasticsearch client did some incompatible changes in one of their patch releases that now cause trouble with spring-data-elasticsearch (still on 8.15.0).

Spring Data Elasticsearch is about to upgrade to 8.15.3 (spring-projects/spring-data-elasticsearch#2993).
