This PR adds support for running test suite using dockerized monerod and monero-wallet-cli

Also this dockerized setup is used in GitHub Actions. Tests are ran upon any push onto master, feature/*, bugfix/* or develop branches. Also against any PRs targeting master branch.

Example CI run https://github.com/mainnet-pat/monero-ts/actions/runs/8894726876/job/24423583889
