We need to check if we can depened on the JS lib web3 that is LGPL-3.0 licensed

[hendrikebbers]

The hedera-mirror-node-explorer depends on web3@4.13.0 (and related libs like web3-eth@4.9.0). The license of the complete web3js project is LGPL-3.0 (see https://github.com/web3/web3.js/blob/4.x/LICENSE).

We need to check if the dependency is ok or need to be fixed. Since hedera-mirror-node-explorer is a product that we release including all dependencies I assume we have a problem here...

More details can be found at #15

We may need to switch to use ethers.js instead (it is MIT licensed)

The explorer dependency on web3 was indirect. Explorer depends on @hedera-name-service/hns-resolution-sdk which in turns used to depend on web3.

This PR has bumped the explorer dependency from @hedera-name-service/hns-resolution-sdk 2.0.11 to 2.0.12, which does no longer depend on web3.

The issue is resolved, I think we can close it.
