feat(cactus-plugin-ledger-connector-ethereum): update web3js to 4.X

- Update web3js packages from 1.10 to 4.0.3 in `cactus-plugin-ledger-connector-ethereum` and
    `cactus-test-plugin-ledger-connector-ethereum`. This allows interacting
    with most recent geth nodes.
- Refactor all ethereum tests. Most of the test cases were duplicated multiple times
    (between different quorum ledger versions test and deployment methods). I've removed all this
    duplication while maintaining similar level of test coverage.
    New tests use Geth test ledger instead of Quorum one.
- Add web3js type conversions methods to minimize impact of poor dynamic typing
    in this early release of 4.X.
- Update API. In 4.X all numeric responses has been converted to BigNum.
    To keep up with this some fields has been changed to string instead of number when necessary.
    Add some missing fields as well.
- Add `estimateMaxFeePerGas` method for estimating current transaction cost.
- Fix invalid `runTransact` response type.
- Add test script for checking integration with Alchemy that must be executed manually
    (it's excluded from CI at the moment) - `geth-alchemy-integration-manual-check.test`.
    Instructions on how to run it has been added to package README.
