Jackson 3 Support

[anbusampath]

Description

Jackson 3 is in final RC phase. Currently elasticsearch-jave client depends on Jackson 2.
It will be useful if elasticsearch-client provide support for Jackson 3(with different maven qualifier) along with Jackson 2.

Spring Boot 4 is migrating to Jackson 3 and backing off to provide Jackson 2 support OOB(Manual is possible).

Hello! We definitely want to provide support for jackson 3 while also keeping jackson 2 support for backwards compatibility. We don't have a timeline yet, but I'll update as soon as I have more details.
