[Java] Remove Jackson from compile-time dependencies for arrow-vector

I would like to upgrade Jackson to the latest version (2.9.5). If there are no objections I will create a PR (it is literally just changing the version number in the pom - no code changes required).

_{**Note**: *This issue was originally created as [ARROW-2501](https://issues.apache.org/jira/browse/ARROW-2501). Please see the [migration documentation](https://github.com/apache/arrow/issues/14542) for further details.*}

Inspecione primeiro o pom Maven de arrow-vector e o pull request #3877 referenciado. Resolva a inconsistência entre o objetivo do título de remover as dependências do Jackson em tempo de compilação e a solicitação do corpo de atualizar o Jackson para 2.9.5; em seguida, verifique a configuração de dependências resultante com o build do projeto.
