Environment variables for session 5 deep speed examples

[marlon-tobaben]

@mszpindler asked the following questions that I transferred this to a new issue as we already merged #77 :

• LUMI-AI-Guide/5-multi-gpu-and-node/run_ds_srun_4.sh

  Lines 39 to 40 in f60c8e2

  	srun --cpu-bind=v,mask_cpu=$CPU_BIND_MASKS singularity run -B ../resources/ai-guide-env.sqsh:/user-software:image-src=/ \
  	$SIF bash -c 'export RANK=$SLURM_PROCID; export LOCAL_RANK=$SLURM_LOCALID; python ds_visiontransformer.py --deepspeed --deepspeed_config ds_config.json'

  Here $SLURM_PROCID and $SLURM_LOCALID also need to be backslashed, aren't they?

• LUMI-AI-Guide/5-multi-gpu-and-node/run_ds_srun.sh

  Lines 39 to 40 in f60c8e2

  	srun --cpu-bind=v,mask_cpu=$CPU_BIND_MASKS singularity run -B ../resources/ai-guide-env.sqsh:/user-software:image-src=/ \
  	$SIF bash -c 'export RANK=$SLURM_PROCID; export LOCAL_RANK=$SLURM_LOCALID; python ds_visiontransformer.py --deepspeed --deepspeed_config ds_config.json'

  Shouldn't there be export RANK=\$SLURM_PROCID; export LOCAL_RANK=\$SLURM_LOCALID;
