MINOR: Update jackson versions to match kafka versions

[Manikumar Reddy (omkreddy)]

jackson-annotations follows a different versioning scheme starting from 2.20, so I’ve added a new property, jackson.annotations.version, for the jackson-annotations library. This property needs to be used by downstream projects.

We will update downstream projects after this

Pull request overview

This PR updates Jackson library versions to align with Kafka's requirements, addressing a versioning scheme change in jackson-annotations starting from version 2.20. The main Jackson version is updated from 2.19.0 to 2.20.1, and a new separate property jackson.annotations.version (set to 2.20) is introduced to handle the divergent versioning scheme for jackson-annotations.

Key Changes

• Updated jackson.version from 2.19.0 to 2.20.1
• Added new jackson.annotations.version property set to 2.20 to accommodate the different versioning scheme

Could we consider reverting this?
the jackson-annotations version is already defined in jackson bom ( we import that). I think that the better way to solve this issue in rest utils would be to remove redefinition of jackson versions instead of adding this property.
I will add it to 8.1.x and 8.2.x ( we have failing builds there after jackson update), but I think the cleaner solution is to remove it altogether.
