Update new kubectl-mongodb path in the precommit hook

[viveksinghggits]

Summary

The precommit hook tries to see if there are any files changed in the multicluster directory and if there are changed files, it runs a go test that creates the updated RBAC files for multicluster.
After we changed the location of the kubectl-mongodb plugin, I missed updating the new path of the plugin in this file. This PR fixes that.

Proof of Work

Run make precommit to make sure it works fine, that would mean that the path of the binaries and the other locations are configured correctly.

MCK 1.2.1 Release Notes

Other Changes

• Optional permissions for PersistentVolumeClaim moved to a separate role. When managing the operator with Helm it is possible to disable permissions for PersistentVolumeClaim resources by setting operator.enablePVCResize value to false (true by default). When enabled, previously these permissions were part of the primary operator role. With this change, permissions have a separate role.
• subresourceEnabled Helm value was removed. This setting used to be true by default and made it possible to exclude subresource permissions from the operator role by specifying false as the value. We are removing this configuration option, making the operator roles always have subresource permissions. This setting was introduced as a temporary solution for this OpenShift issue. The issue has since been resolved and the setting is no longer needed.
