ORC-1019: Remove redundant Jackson dependencies in bench module (#930)

### What changes were proposed in this pull request?

This PR aims to remove redundant jackson dependencies.
Unfortunately, ORC-946 forgot to remove the bench dependency on jackson. In fact, the bench module does not directly depend on jackson, only spark indirectly depends on the specified version of jackson. 

### Why are the changes needed?

Minimising dependencies.

### How was this patch tested?

Pass the CIs.

Closes #928
