Use better icons for llama, Gemini, and other models, Issue-#675

[hpatel292-seneca]

In this PR, I’ve updated the logoUrl function in ChatCraftModel.ts to improve the icon selection for several new AI models, including Llama, Gemini, Mixtral, and Phi. I’ve added relevant icons for these models and ensured they display properly in the UI. The new icons were sourced and added to the assets folder, and now each model from providers like Meta, Google, and others has a unique, recognizable logo. This helps enhance the user interface by providing more visually distinct and accurate model representations.

Lets reduce the size of these as much as you can. We're only going to show them in a very small width x height area, and also the quality can be reduced.

Use something like https://squoosh.app/ and make them all PNG.

[hpatel292-seneca]

I converted the jpg to png but the size of new logos is kind of same compare to other logos.

Probably the existing ones need to get fixed too, but this looks reasonable.

[hpatel292-seneca]

I didn't push new changes. Let me do that first

[humphd]

I was just going to ask... :)

[hpatel292-seneca]

I pushed new changes.

[humphd]

Let's try it. Thanks for doing this @hpatel292-seneca, it's appreciated.

Testing this in prod, looks good!

One thing I wonder about: should we change the llama check so it just looks for llama in the name? Otherwise only meta-llama comes up with an icon.

I'd be tempted to use it for all of them, since it's the same model.

[hpatel292-seneca]

I would love to update it. Should I?

[humphd]

In a new PR? sure.

[hpatel292-seneca]

So could you please open new issue or should I send PR directly?

[humphd]

Just send a PR, reference this issue (e.g., "Part of #690")
