Type.FullName contains Type.AssemblyQualifiedName for generic arguments

### Description

For a type, FullName returns FQAN for generic type arguments. It is inconsistent with what FullName returns for non-generic types.

### Reproduction Steps

```
using System;

public class Program
{
public static void Main()
{
Console.WriteLine(typeof(int).FullName);
Console.WriteLine(typeof(int?).FullName);
}
}
```

### Expected behavior

System.Int32
System.Nullable`1[[System.Int32]]

### Actual behavior

System.Int32
System.Nullable`1[[System.Int32, System.Private.CoreLib, Version=8.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e]]

### Known Workarounds

This method returns the full type name with the assembly name.

```
public static string GetStringRepresentation(this Type type)
{
if (type.IsGenericType)
{
var genericTypeDef = type.GetGenericTypeDefinition();
var args = type.GetGenericArguments();

var simplifiedArgs = string.Join(", ", args.Select(arg => $"[{arg.GetStringRepresentation()}]"));

return $"{genericTypeDef.FullName}[{simplifiedArgs}], {type.Assembly.GetName().Name}";
}

return $"{type.FullName}, {type.Assembly.GetName().Name}";
}
```

The following code:
```
Console.WriteLine(typeof(int).GetStringRepresentation());
Console.WriteLine(typeof(int?).GetStringRepresentation());
```
Results in:
```
System.Int32, System.Private.CoreLib
System.Nullable`1[[System.Int32, System.Private.CoreLib]], System.Private.CoreLib
```

### Other information

Ideally there could be a property that returns FQAN, but without version and token. So this information could be serialized and used during deserialization even when the version of the assembly changes.
