Warnings for non-existent property 'INVALID_ALT_NUMBER'

[rootulp]

I observed the following warnings when running yarn install:

(node:7265) Warning: Accessing non-existent property 'INVALID_ALT_NUMBER' of module exports inside circular dependency
(node:7265) Warning: Accessing non-existent property 'INVALID_ALT_NUMBER' of module exports inside circular dependency

This seems caused by antlr/antlr4#2834 which gets pulled in by solhint

[rootulp]

The latest release of solhint (3.3.6) depends on antlr 4.7.1 (see here) which still contains this issue so upgrading won't resolve. We need antlr 4.9

We can track protofire/solhint#309 and upgrade solhint after that is resolved
