fix(controller): remove PUBLISH_UNPUBLISH_VOLUME capability for SMB

The SMB CSI driver does not implement ControllerPublishVolume or ControllerUnpublishVolume
since SMB shares are mounted directly by nodes and do not require controller-side attach/detach.

Removing the ControllerServiceCapability_RPC_PUBLISH_UNPUBLISH_VOLUME capability avoids
advertising unsupported functionality and allows the sanity test suite to pass.

This change does not impact node-side STAGE_UNSTAGE_VOLUME support, which remains fully functional.
