[OSS-ONLY] Update antlr to 4.13.2 (#3067)

Update the antlr version to 4.13.2. This dramatically improves ANTLR parsing performance for certain queries, reducing their execution times by up to 40%.

Note that this will require developers to have Java 11+ installed in order to develop locally.

Also update the github actions to make it so that previous versions of Babelfish will be compiled using the original antlr-4.9.3 version. This is purely a fix for testing.
