addChain should return if a chain is already supported

[pyramation]

So what im seeing now is that we are using the useChains hook, with some chains in there that are already in my Keplr wallet, but still they pop up as if they are new chains and need to be added to Keplr as new chain

cosmos-kit/wallets/keplr-extension/src/extension/client.ts

Lines 123 to 140 in d5f38a3

	async addChain(chainInfo: ChainRecord) {
	const suggestChain = chainRegistryChainToKeplr(
	chainInfo.chain,
	chainInfo.assetList ? [chainInfo.assetList] : []
	);
	if (chainInfo.preferredEndpoints?.rest?.[0]) {
	(suggestChain.rest as string | ExtendedHttpEndpoint) =
	chainInfo.preferredEndpoints?.rest?.[0];
	}
	if (chainInfo.preferredEndpoints?.rpc?.[0]) {
	(suggestChain.rpc as string | ExtendedHttpEndpoint) =
	chainInfo.preferredEndpoints?.rpc?.[0];
	}
	await this.client.experimentalSuggestChain(suggestChain);
	}

for now, only do keplr mobile and keplr extension, you can leverage JSON from

modify this to have supportedChains? property that stores an array of chain names

cosmos-kit/packages/core/src/types/wallet.ts

Line 77 in d5f38a3

export interface Wallet {
