infra warp checker does not detect new chains

[ltyu]

Problem

Currently, the infra warp checker only uses the existing onchain routers list for enrollment violations.

hyperlane-monorepo/typescript/sdk/src/router/RouterApps.ts

Lines 46 to 56 in d6724c4

	override async remoteChains(chainName: string): Promise<ChainName[]> {
	const router = this.router(this.contractsMap[chainName]);
	const onchainRemoteChainNames = (await router.domains()).map((domain) => {
	const chainName = this.multiProvider.tryGetChainName(domain);
	if (chainName === null) {
	throw new Error(`Chain name not found for domain: ${domain}`);
	}
	return chainName;
	});
	return onchainRemoteChainNames;
	}

However, if we are adding new chains to the config, it won't show them as violations.

It should show that the existing routers have not enrolled the expected new chains.
