fix(rbac): change job api group to batch

[vdice]

Describe your changes

• Updates the job api group to batch for correct RBAC

Note: I'm not yet able to fully test via the make build deploy flow as RBAC issues remain. Next up are node permissions, which will require a rewrite of node_controller.go.
