Breaking change in gptel: gptel-models as symbols

[karthink]

Just a heads-up that in preparation for media/images, function calling and json support in gptel, I now require gptel-model to be a symbol, i.e. (setq gptel-model 'gpt-4o-mini) instead of (setq gptel-model "gpt-4o-mini").

This is a breaking change but I'm trying to paper over this difference: specifying gptel-model as a string should still work fine, but with a warning. Sorry for the trouble!

This will be effective in gptel version 0.9.5, which I'll be tagging today. In a future version the warning will be upgraded to an error, hopefully giving everyone enough time to make the change.

Thanks for the heads up. Fortunately I only use gptel's gptel-request to make calls for model queries right now, so I don't think I need to do anything on my end.
