## Summary A small cleanup in parser code in the ES|QL AST package. We want to show users readable syntax error token names like `[` and `(` (instead of `LP`), however, we should not monkey-patch ANTLR generated files to achieve this. Instead, this PR moves the message improvement code to the validation & autocomplete package, where the messages are actually used. ### Checklist - [x] [Unit or functional tests](https://www.elastic.co/guide/en/kibana/master/development-tests.html) were updated or added to match the most common scenarios (cherry picked from commit 750cc7c)
