Gemini Support

Hey!

This morning I picked up the new Gemini chatbot from Google, it has an API key and so I wondered if it could be hooked up to mods?

• https://cloud.google.com/vertex-ai/docs/generative-ai/model-reference/gemini

maybe i'll get inspired to try adding this myself sometime, until then I open this
