Update compiler-error-c2061.md

It wasn't as clear what the fix using typename was. You can sort it out, but I decided to make it more explicit for those reading quickly.

 C2061 can occur if you pass an instance name to [typeid](../../extensions/typeid-cpp-component-extensions.md):
 
 ```cpp
 // C2061b.cpp
 // compile with: /clr
-ref struct G {
+ref struct G
+{
    int i;
 };
 
-int main() {
-   G ^ pG = gcnew G;
+int main()
+{
+   G ^pG = gcnew G;
    System::Type ^ pType = typeid<pG>;   // C2061
    System::Type ^ pType2 = typeid<G>;   // OK
 }
