Removes additional sbatch and fixes default profile in cluster deploy…

…ment (isaac-sim#1229)

# Description

In the slum workflow, currently, there was an unnecessary `sbatch`
command; this PR removes it. In addition, the profile argument was
marked as optional, but when a job was submitted, and job arguments were
passed, it became necessary. This PR fixes this behavior.
