Alma9 setup fails due to Unknown repo powertools

**CC**: `8.7.1`
**Slurm Proj**: `3.0.11`
**OS**: `almalinux:almalinux-x86_64:9-gen2:9.4.2024080501`

Trying to start Slurm cluster running marketplace Alma9 image and it fails to install. I pulled the failing command from `azure-slurm-install.log` and tried to run manually:

```
[root@jm-slurm-alma9-scheduler yum.repos.d]# /opt/cycle/jetpack/system/bootstrap/azure-slurm-install/rhel.sh 'scheduler' '24.05.4-2' 'False'

Complete!
Error: Unknown repo: 'powertools'
```

in Alma9 there is no powertools repo and `perl-Switch` is in the crb repo. The `rhel.sh` [script](https://github.com/Azure/cyclecloud-slurm/blob/b26ab06176eb0f64406df25d614e1f9fe82154b2/slurm/install/rhel.sh#L31) currently uses `dnf -y --enablerepo=powertools install -y perl-Switch` that is failing. The manual command `dnf -y --enablerepo=crb install -y perl-Switch` worked.
