Clarify SLURM login node documentation (#3080)

This PR lists the SLURM login nodes in the documentation to be extra
clear on which nodes can be used to submit jobs to the SLURM cluster.

 Before we dive into the details, let's define some common terms used in SLURM:
 
-- **Login node**: A node that users log into to submit jobs to the SLURM cluster. This is where you will interact with the SLURM cluster.
-- **Compute node**: A node that runs jobs submitted to the SLURM cluster. This is where your job will run.
+- **SLURM Login node**: A node that users log into to submit jobs to the SLURM cluster. This is where you will interact with the SLURM cluster.
+- **SLURM Compute node**: A node that runs jobs submitted to the SLURM cluster. This is where your job will run.
 - **Partition**: A logical grouping of nodes in the SLURM cluster. Partitions can have different properties (e.g. different resource limits) and are used to organize resources.
 - **Job**: A unit of work submitted to the SLURM cluster. A job can be interactive or batch.
 - **Interactive job**: A job that runs interactively on a compute node. This is useful for debugging or running short tasks.

 ## Quick Start
 
-### SSH Into a SLURM Node
+### SSH into a SLURM login node
 
-To submit jobs to the SLURM cluster, you must first SSH into one of the SLURM login nodes.
-During the beta, they are machines labelled `SL` in the [machine list](/machines#general-use-machines).
-After the beta, all general-use machines will be SLURM login nodes.
