build: implement integration test for zkSync contracts

[JuArce]

This issue is a continuation of #171

To assure correct functionality of ZKSync contract in every future change, an integration test will run inside the CI (github workflow) that deploys the necesarry contracts and executes the whole process of a bridge:
-set_order
-transfer
-claim_payment

If this test fails: either:
-a breaking change is trying to be pushed to main, which is a mistake.
-the integration test must be updated (for example the name of a called function has been updated)

For this, the Dockerized L1-L2 nodes is currently being used, but setup-dev is under analysis of being used, since it is more used around the industry.
