Update VSCode cluster connection instructions for new configuration

[CarlosLopezElorduy]

Revise the documentation to reflect changes in the cluster configuration, including updated resource allocation commands and SSH settings for connecting to the IRB cluster.

Thanks for the update Carlos,

Actually I do it in a different way - I use the SBATCH command to submit the job and I always call the same node, cpus and memory directly in the sbatch file. This is my current header:

❯ cat .local/bin/vscode-it
#!/bin/bash

#SBATCH --job-name="code-client"
#SBATCH --cpus-per-task=16
#SBATCH --nodelist=irbccn25
#SBATCH --partition=bbg_cpu_zen4
#SBATCH --mem=32G
#SBATCH --qos=interactive
#SBATCH --time=30-00:00:00     # walltime

set -xe

/usr/sbin/sshd -D -p 3131 -f /dev/null -h ${HOME}/.ssh/id_ecdsa

then I run it from the login node with:

sbatch vscode-it

This avoids the problem of allocating a different node every time and then losing the history for your opened sessions on a specific node in vscode, then it reduces the steps from 3 to just one, since the job is directly launched from the login node, no need for a screen nor an interactive session.

Having said so, your method works as well, and it's fine to me, up to you. If you want to merge go ahead!
