Clarify example in IDE0002 to include the class

The example

```csharp
static void M1() { }
static void M2()
{
// IDE0002: 'C.M1' can be simplified to 'M1'
C.M1();

// Fixed code
M1();
}
```
presumably is in a class C, but a new developer or developer new to C# might not be able to draw that conclusion. For clarity's sake the example could include the class C:

```csharp
class C
{
static void M1() { }
static void M2()
{
// IDE0002: 'C.M1' can be simplified to 'M1'
C.M1();

// Fixed code
M1();
}
}
```

I don't know VB but I can add to the C# example in a PR if it's desired.
