Update substrate integration test environment (#931)

- Switched to the pullparitytech/contracts-ci-linux:production image for having a node that will always be up-to-date
- Bump many npm deps in the testing frameworks
- Fix all test specs so the work again with the new runtime and updated deps
- Disable discovered regressions and explicitly test for issue 666

 ## Build for Substrate
 
+### Status
+:warning: Solang was developed against Substrate v3.0. It has been a while since the last time the Substrate target was worked on, which introduced a few known regressions. Currently, the following is known to **not** work with recent Substrate versions:
+
+* Function call arguments of type `address`
+* Function return values of type `address`
+* Cross-contract calls
+* Events with indexed fields
+
+Maintenance on the Substrate target has now resumed and we are working on fixing these issues.

 Parity Substrate
 ================
 
-Solang works with Parity Substrate 2.0 or later.
+Solang works with Parity Substrate 3.0. Note that for recent Substrate Version, cross-contract calls as well as using `address` 
+type as function argument or return values are not supported. We are currently working on fixing any regressions.
 
 The Parity Substrate has the following differences to Ethereum Solidity:
