[feature] an option to disable labels in appkit-network-button

[art-eth]

What problem does this new feature solve?

It would be great if we could disable labels and show only network's icon on the button. It would be developer's responsibility to make sure the icon exists if custom chain is defined (not sure if Reown guarantess icons for all the supported networks?).

Why?
On mobiles, it's important to keep things clean as there is not much space sometimes.
