Correct kubectl-mongodb path for command prepare_local_e2e

[viveksinghggits]

Summary

When we change the directory of kubectl-mongodb from public/tools/multicluster to cmd/kubectl-mongodb we change the source file build_multi_cluster_kubeconfig_creator.sh to use the new path but I missed updating the new path in the file funcs/multicluster. This PR fixes that problem and updates the path to point to the correct location.

Proof of Work

Run make prepare_local_e2e, that will build the kubectl-mongodb binary and use the kubectl mongodb multicluster command to setup the multicluster environment.

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.

The CI is failing because of a known issue https://mongodb.slack.com/archives/CGLP6R2PQ/p1753439731022119?thread_ts=1753361900.361289&cid=CGLP6R2PQ, and it's recommended to ignore the failure in the CI. I will go ahead and merge the PR.
