ci(docs): add llama-stack version to distro docs (#53)

# What does this PR do?
Adds the current Llama Stack version being used in the container to the docs

## Test Plan
Take a look!


## Summary by CodeRabbit

* **Documentation**
  * Updated distribution README to announce upstream Llama Stack v0.2.22 with a link.
  * Generated distribution docs now automatically display the detected Llama Stack version for clarity and traceability.
* **Chores**
  * Improved doc-generation to auto-inject detected version and to present clearer, user-facing error messages when version information is missing.
