Fix Inf2 benchmark

[namannandan]

Description

Inf2 benchmarks have been failing due to the following reasons:

1. The latest version of torch-neuronx requires torch 2.1.2 and torch was pinned to 1.13
2. Although setuptools is pinned, it was getting upgraded when loading the benchmark models due to installation of custom dependencies ex: torch-neuronx. Related issue: ImportError: cannot import name 'packaging' from 'pkg_resources' #3176

Fix:

1. Pin torch to a know supported version for neuronx
2. Update Inf2 model artifacts to not use custom dependencies since these are already setup by install_dependencies.py script before running the benchmark.
