Missing pprof routes

[hherman1]

What happened?

Several pprof routes are missing and 404 from the pprof index. This code fixes it:

	pprofs := []string{"goroutine", "block", "allocs", "mutex", "threadcreate"}
	for _, prof := range pprofs {
		err = info.Router.Get("/debug/pprof/"+prof, pprof.Handler(prof))
		if err != nil {
			return nil, fmt.Errorf("register %v route: %w", prof, err)
		}
	}

The reason is that the witchcraft router does not support handlers accepting subpaths, and the net/http/pprof Index handler tries to automatically handle these routes.

What did you want to happen?
