Rename com_github_antlr_antlr4_runtime_go_antlr to com_github_antlr_antlr4_runtime_go_antlr_v4

[satreix]

Describe the bug

Recent version of gazelle map "github.com/antlr/antlr4/runtime/Go/antlr/v4" to "com_github_antlr_antlr4_runtime_go_antlr_v4" and not "com_github_antlr_antlr4_runtime_go_antlr".

This causes the following error for projects that import cel-go with bazel and gazelle:

ERROR: external/com_github_google_cel_go/parser/BUILD.bazel:7:11: no such package '@com_github_antlr_antlr4_runtime_go_antlr//': The repository '@com_github_antlr_antlr4_runtime_go_antlr' could not be resolved: Repository '@com_github_antlr_antlr4_runtime_go_antlr' is not defined and referenced by '@com_github_google_cel_go//parser:go_default_library

To Reproduce

Use a recent version of go/bazel/gazelle and depend on cel-go v0.14. This is done in satreix/everest#466 (you do need to drop the patch introduced in the PR for the issue to trigger).

Expected behavior

Gazelle should not be tripped by the naming of com_github_antlr_antlr4_runtime_go_antlr in this repo.

Additional context
IIUC this was introduced with #644

Thank you, @satreix. I'll make to bump the WORKSPACE naming and associated bzl files and create a point release mid-week
