*:go_default_library should be alias of *:xyz_go_proto

I'm seeing the following error when building a go binary that depends on `semver.proto` and `remote_execution.proto`:

```
$ bazel build //:test
INFO: Invocation ID: 5938ca3c-1dae-404a-833e-20b364aed4bb
INFO: Analyzed target //:test (1 packages loaded, 2 targets configured).

//build/bazel/semver:go_default_library
Set "importmap" to different paths in each library.
This will be an error in the future.

```

BUILD:
```starlark
go_binary(
name = "test",
srcs = [
"test.go",
],
deps = [
"//build/bazel/remote/execution/v2:go_default_library",
"//build/bazel/semver:semver_go_proto",
],
)
```

test.go:
```go
package main

import ()

func main() {
}
```

Start by locating the BUILD definitions for //build/bazel/semver:semver_go_proto, //build/bazel/semver:go_default_library, and the remote execution Go target. Reproduce the warning with the shown bazel build //:test command; done means the default Go library resolves as an alias of the proto target without duplicate package providers.
