Issue: x/telemetry/godev/cmd/telemetrygodev: test fails when run in a standalone module
Labels: Testing,NeedsInvestigation

### Go version

6e7aee5f6bdcf2823be358d6e4452b5e2fafb8ed

### Output of `go env` in your module/workspace:

```shell
N/A
```


### What did you do?

https://build.golang.org/log/a1fcb0cfb4ce3595205204cea723c2d7a5c447e5

### What did you see happen?

```
2024/01/22 21:17:02 open ../../../config/config.json: no such file or directory
FAIL	golang.org/x/telemetry/godev/cmd/telemetrygodev	0.278s
```

Note that the `android` builder runs tests by copying the entire module containing the package to the builder, similar to running `go test` on the package from outside of its module.

The `replace` directive added in https://go.dev/cl/499918 causes the `golang.org/x/telemetry/godev` module to depend on an invalid version of `golang.org/x/telemetry`, but if you also `go get` a valid version of that module, the failure is also reproducible on any platform by running the test from the module cache:

Per https://github.com/golang/go/issues/34352#issuecomment-1650335903 the test failure should also be reproducible on the LUCI builders, but for some reason it is not — no failures are showing up on https://ci.chromium.org/p/golang/g/x-telemetry-gotip/console. I will follow up on that separately.

### What did you expect to see?

All tests passing, including when run from within the module cache.
