fix: replace run-with-testrpc with ganache

[JGiter]

Description

run-with-testrpc is not maintained for 4 years already, which is possilbe reason of https://github.com/energywebfoundation/iam-client-lib/actions/runs/5219187364/jobs/9420739666?pr=695
As it turned out the real reason of not detecting of network is localhost in rpc url. It should be 127.0.0.1. Not crear why or how this changed. ethers documentation provides example of creating JsonRpcProvider with http://localhost:8545 url
Even if problem was not caused by run-with-testrpc it still seems usefull to replace it
