lint: synchronise linting rules of repositories

[benceharomi]

What ❔

Synchronise the linting and formatting rules of the repositories, use the configs from the era-system-contracts repository as a base.

Steps:

1. update the linf/format configs of the ethereum dir
2. add the lint/format configs to the zksync dir
3. add missing packages, update outdated packages to the the same version as in the era-system-contracts
4. format/lint all of the files in both dirs
5. add zksync linting to the CI

Why ❔

Currently the era-contracts and the era-system-contracts repositories have different linting and formatting rules, the goal of this task is to synchronise them.
