ci: test safety with starter

We are now testing the safety capability with the starter image. This
includes a few changes:

* Enable the safety integration test
* Relax the shield model requirements from llama-guard to make it work
  with llama-guard3:8b coming from Ollama
* Expose a shield for each inference provider in the starter distro. The
  shield will only be registered if the provider is enabled. Shields
  will be added if the provider claims to support a safety model
* Missing providers models have been added too
* Pointers to official documentation pages for provider models support
  have been added
