Describe the bug

CodeLens.references is disable by default, but it has a very useful information. I enabled it using the config below:

  "go.enableCodeLens": {
    "references": true,
    "runtest": true,
  },

The first off thing was that guru do not show on Go: Install/Update Tools and I needed to install using go get -u golang.org/x/tools/cmd/guru.

All interface reference count is 0 references.

Steps to reproduce the behavior:

This simple code:

package main

import "fmt"

type SayHi interface {
	Hi() string
}

type HiMan struct{}

func (HiMan) Hi() string {
	return "Hi Man"
}

func main() {
	sayHi(HiMan{})
}

func sayHi(s SayHi) {
	fmt.Println(s.Hi())
}

With the language server enabled, the extension does not include guru as one of the tools. Since this feature is not implemented in gopls (see: golang/go#40862), perhaps we should consider including it in the list of tools even when the language server is enabled.

We are no longer maintaining guru in favor of gopls. If you would like to see support for this feature from gopls, please add your support to golang/go#40862.

The feature relies on guru and unfortunately, guru is no longer maintained and won't work well in Go module mode (which is the default in the latest Go version) even when we let guru handle this when the language server is enabled. Let's close this issue in favor of golang/go#40862.
