Specifies additional environment variables to set when the target is
executed by bazel run.
This attribute only applies to native rules, like cc_binary, py_binary,
and sh_binary. It does not apply to Starlark-defined executable rules.
NOTE: The environment variables are not set when you run the target
outside of Bazel (for example, by manually executing the binary in
bazel-bin/).
