 * ```ts

 *
 * const chain = defineAlchemyChain({
 *  chain: sepolia,

 * @param {AlchemyChainConfig} params The parameters for defining the Alchemy chain
 * @param {Chain} params.chain The original chain configuration
 * @param {string} params.rpcBaseUrl The Alchemy-specific RPC base URL
 * @returns {Chain} The updated chain configuration with the Alchemy RPC URL added
