CAMEL-22857: fix Jackson 2 dependency management for Jackson 3 migration

Replace the explicit jackson-annotations managed dependency with a
Jackson 2 BOM import. This ensures all Jackson 2 artifacts (annotations,
core, databind) stay coherent at the same version.

Previously, only jackson-annotations was managed at 2.20 while
jackson-databind was unmanaged, causing langchain4j (which transitively
brings jackson-databind 2.21.1) to fail with NoClassDefFoundError for
JsonSerializeAs (introduced in annotations 2.21).

Also bumps jackson2-version from 2.20.2 to 2.21.1 to match the version
used by transitive dependencies like langchain4j.
