Spring Boot 4 requires Jakarta EE 11. Jersey 4 will support EE 11 but
its release schedule is uncertain. Furthermore, Jersey does not yet
support Jackson 3 and there's no clear timeline for when Jackson 3
will be supported.
In light of the above, this commit removes support for Jersey.
Reinstating support can be considered once there's a Jersey GA that
supports Jakarta EE 11 or its clear that one will be available in
time for Boot's GA in November. Ideally, support for Jackson 3 would
also be available before reinstating Jersey support.

Previously, the DataSource initialization would back off without
spring-boot-jdbc but spring-boot-sql was a required dependency.
Without spring-boot-sql, a failure would occur due to the absence
of OnDatabaseInitializationCondition.
This commit updates the auto-configuration so that spring-boot-sql
is now an optional dependency and DataSource initialization
backs off in its absence.
