Accept null for tasks_per_node while retaining 1 as the default. This allows
Submitit to omit --ntasks-per-node from Slurm submissions.

Add regression coverage, documentation, and a news fragment.

Thanks @OhadRubin! I took this over, kept 1 as the default per @Jasha10’s compatibility suggestion, and added coverage and docs for explicit null.
