8ed817e fix: make regtest default on wallet_example_rpc (Luis Schwab)

Pull request description:

  ### Description

  This PR makes `Regtest` the default network on `wallet_example_rpc` and updates the README accordingly.

  ### Notes to the reviewers

  It had `Testnet` as the default network, `8332` as the default port and `481824` as the starting height; now everything is `Regtest`.
