docs(gemini): image_url is not supported — it returns 422 (#40)

Signed-out Gemini accepts the upload and then refuses to answer about it
(PERMISSION_DENIED from its own generate call), so scrapebadger now 422s
image asks immediately instead of charging for a request that cannot
succeed. The parameter stays on the signature — removing it would break
callers — but the docstring no longer promises an answer. chatgpt.ask
takes an image and answers about it.

See scrape-badger/scrapebadger#1614.
