Show tuples using native syntax

[ap0llo]

For a member that uses C# tuples e.g.

public (string, int) Method() 
{ }

the definition included in the documentation uses the generic syntax for ValueTuple:

public ValueTuple<string, int> Method();

• In these cases, the C# tuple syntax (string, int) should be used.
• When feasible, the definition should also include the tuple element names.
