[docs] update the zero_to_hero_guide llama stack version to 0.1.0 (#960)

# What does this PR do?

The Zero to Hero guide currently references an older 0.0.61 llama-stack
version. Using the most recent stable release of the product in the
documentation, would help the users not to go through any issues from
the older llama-stack versions.

## Test Plan

I have ran the workflow locally using the proposed version change and I
am able to proceed further ahead without any issue.
