I wanted to use env_inherit in go_test to pass through an environment variable

The environment variable pass through successfully

What did you see instead?

env_inherit is not supported.

---

go_test currently allows defining fixed environment variables through env, but not passing through inherited environment variables. This was added to starlark support in Bazel 5.2 (https://blog.bazel.build/2022/06/08/bazel-5.2.html#starlark)
