I now see the same error in Edge that we used to have in Chrome when we were migrated to the new type: the LanguageModel.prompt method exists, but throws an unsupported input error with the new rich type. Edge Canary works. I'll take a look at detecting the Edge version in isAvailable.

Problem Statement
Vertex doesn't require callers to pre-specify expected input types. Could we make the hybrid API do the same?
Now that Edge has added support for text inputs, but not image inputs, we need to remove the default image input type, which further motivates this change.
Solution
Since the AI SDK request object contains the intended input types, we can extract those and reformat them into the format expected by Chrome.
