Currently, if you cmd+shift+P and choose Go: Add Import. The list of imported file looks incorrect. For example, packages within the same module do not show up.

To reproduce, go into a module repo such as golang.org/x/tools and open a Go file such as internal/lsp/source/rename.go.

Try to run the Go: Add Import and notice the list does not include most of the packages that you expect within the tools repo. Or even sometimes you get this error:

Could not find packages. Ensure `gopkgs -format {{.Name}};{{.ImportPath}}` runs successfully.

As a solution, I don't think we have to call out into gopkgs anymore as we can just call go list directly to get all importable paths within a directory.
