chore: synchronise linting rules of repositories

[benceharomi]

!!! Submodules must be updated before merge !!!

The following PRs are a requirement for these changes to work:
matter-labs/era-contracts#66
matter-labs/era-system-contracts#49

What ❔

Updated format and lint process of the contracts and system-contracts submodules. From now on the formatting and linting commands of the main repository ignores the submodules' files, and calls their format and linting commands instead.

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.
