Create GenLayer client like viem examples

[AgustinRamiroDiaz]

Viem has examples for many clients in their public repo

• https://github.com/wevm/viem/blob/main/src/clients/createTestClient.ts
• https://github.com/wevm/viem/blob/main/src/clients/createWalletClient.ts
• https://github.com/wevm/viem/blob/main/src/clients/createPublicClient.ts

Which seem to compile without the as unknown patch that we do

genlayer-js/src/client/client.ts

Lines 21 to 38 in 95ae405

	// Extend Viem client to work with GenLayer-specific chains (simulator, testnet, etc.)
	export const createClient = (config: ClientConfig = {chain: simulator}) => {
	// Determine the RPC URL based on the provided configuration or default to the simulator's RPC UR
	const chainConfig = config.chain || simulator;
	const rpcUrl = config.endpoint || chainConfig.rpcUrls.default.http[0];
	// Create a Viem client connected to the GenLayer Simulator (or custom chain)
	const baseClient = createViemClient({
	chain: chainConfig,
	transport: http(rpcUrl),
	...(config.account ? {account: config.account} : {}),
	})
	.extend(publicActions)
	.extend(client => accountActions(client as unknown as GenLayerClient<SimulatorChain>))
	.extend(client => transactionActions(client as unknown as GenLayerClient<SimulatorChain>))
	.extend(client => contractActions(client as unknown as GenLayerClient<SimulatorChain>));
	const genLayerClient = overrideContractActions(baseClient as unknown as GenLayerClient<SimulatorChain>);

We should follow a similar approach so that we have better TypeScript usage
