Describe the bug

I'm not sure where this originating, but I think that antlr/antlr4#2834 is the root cause.

I see this when running Composer with node 14.15.x:

(node:94216) Warning: Accessing non-existent property 'INVALID_ALT_NUMBER' of module exports inside circular dependency

Related to #1061

Expected behavior

The issue linked above suggests that this has been fixed in a newer version of antlr4.

Additional Information

This does not seem to break anything, but I'm trying to clean up the node warnings in Composer and came across this, so maybe something to look into during a quality milestone post //build.
