exporting Google models as DEFAULT_MODEL doesn't work; neither does specifying one with --model

[AndreLeifert]

What happened?

cat /tmp/transcript.txt | fabric --pattern summarize --model gemini-1.5-flash results in an error while cat /tmp/transcript.txt | fabric --pattern summarize --model models/gemini-1.5-flash works

The "error" is in fetch_available_models inside utils.py - genai.list_models() precedes model names by models/. I am opening a fixing PR.
