Gemini Pro Exp edit mode Vertex AI / Gemini and Gemini Pro 1.5 Pro 002 edit mode

[Jasmin68k]

Issue

Hello!

Just two observations with v0.60.1:

1. aider uses whole edit mode for vertex_ai/gemini-pro-experimental (probably because it doesn't know it), but the model is the same as gemini/gemini-1.5-pro-exp-0827, see https://cloud.google.com/vertex-ai/generative-ai/docs/multimodal/gemini-experimental, so it should probably use diff-fenced, too.

2. aider uses diff edit mode for gemini/gemini-1.5-pro-002, while all other Gemini Pro models use diff-fenced. On https://cloud.google.com/vertex-ai/generative-ai/docs/multimodal/gemini-experimental, it says diff-fenced also for gemini/gemini-1.5-pro-002. I don't know, which mode is better for the model (maybe the newer Gemini Pro really works better with diff?), but either aider's model config or the benchmark page is wrong.

Hope it helps.
