feat: allow attach ChainApi interface to useClient & useTypink

[sinzii]

We can now attach ChainApi interface into useTypink or useClient hooks:

const { client } = useTypink<PolkadotApi>(); 
// or
const { client } = useClient<PolkadotApi>();

// client will now have type of `CompatibleSubstrateClient<PolkadotApi>`
