Add Fantom Icon to assets/chains.tsx and display it when the chain is selected

It would be nice to add support for more chains to have an icon instead of just showing a default one.

API Reference for Chain Icon: https://docs.family.co/connectkit/api-reference#additional-components-chain-icon

Would it be possible to add Fantom to the 'list'? Link to Fantom icon, just in case: https://cryptologos.cc/fantom. Thank you in advance! :)
