Repo should enforce the node version

I was running the template with node 16 and getting the following error:

% npm start

> pimlico-tutorial-template@1.0.0 start
> tsx index.ts

HttpRequestError: HTTP request failed.

URL: https://rpc.ankr.com/eth_sepolia
Request body: {"method":"eth_chainId"}

    at attemptRetry (file:///Users/user/dev/pimlico-tutorial-1/node_modules/viem/utils/promise/withRetry.ts:44:22)

Updating to node 18 fixed the issue.
