是否考虑更新依赖到“github.com/antlr/antlr4/runtime/Go/antlr/v4”模块

`v1`版本的模块“github.com/antlr/antlr4/runtime/Go/antlr”好像已经“deprecated”了

```
// Deprecated: Please switch to the new v4 module path: github.com/antlr/antlr4/runtime/Go/antlr/v4 - see https://github.com/antlr/antlr4/blob/master/doc/go-target.md
module github.com/antlr/antlr4/runtime/Go/antlr
```
新的`v4`模块似乎对Go下游兼容性更好而且能有效避免`ambiguous import`的问题。

Search the Go project for references to github.com/antlr/antlr4/runtime/Go/antlr and inspect the dependency declarations. Review the linked antlr4 Go module guidance first, then update the project to the v4 module path and run the available Go tests; done means the project builds without ambiguous-import errors.
