Golang x/tools/gopls: Rename: missing type for selector in satisfy.(*Finder).expr

#!stacks
"runtime.sigpanic" && "satisfy.(*Finder).expr:+75"

Issue created by stacks.

    case *ast.SelectorExpr:
        if _, ok := f.info.Selections[e]; ok {
            f.expr(e.X) // selection
        } else {
            return f.info.Uses[e.Sel].Type() // qualified identifier                 <----------- panic 
        }

This is related to https://github.com/golang/go/issues/71572 and https://github.com/golang/go/issues/73109: satisfy was called on ill-typed code; and the resolution is the same: wait for https://github.com/golang/go/issues/70638.

Although this issue is in the gopls/backlog milestone, it belongs in the hypothetical milestone "first gopls release after the next Go release (1.25)," since the next Go release should have implemented #70638.
