Ubuntu pkgs mismatched with Disable PMC true

**ENV**:
CC v8.7.1
Slurm project 3.0.9 and 3.0.11
Ubuntu 22.04 HPC image

**ISSUE**:
With `Disable PMC` box checked in cluster `Advanced Settings` panel, the Slurm version of compute nodes have a newer version of Slurm than scheduler and can not register when coming online. The version of Slurm specified in the Cluster settings is ignored.

With `Disable PMC` checked, it appears as though latest version of Slurm is being installed from the package manager. Over time the version available in the package manager will change and compute nodes can will have a newer version than the scheduler.

**WORKAROUND**:
Uncheck the `Disable PMC` box or manually update/upgrade the scheduler to the newer version. When PMC is used the Slurm versions have an `apt-mark hold` configured for Slurm to prevent upgrade but that isn't present when PMC is disabled.
