Fix defunct example and update C2735 error reference

[Rageking8]

Update error message, fix defunct example, and update ms.date metadata.

Example: inline int

Old example that no longer generates C2735:

// C2735.cpp
void f(inline int){}   // C7643

Visual Studio 2022

C2735.cpp
C2735.cpp(2): error C7643: 'unnamed-parameter': 'inline' specifier cannot appear on a function parameter

Example: virtual int

New example that generates C2735. Tested practically all other keywords and it seems only virtual emits it.

// C2735.cpp
// compile with: /c

void func(virtual int) {}   // C2735

C2735.cpp
C2735.cpp(4): error C2735: 'virtual' keyword is not permitted in formal parameter type specifier

Example: virtual int i

Tried adding an identifier for the parameter, but that changes the error emitted:

// C2735.cpp
// compile with: /c

void func(virtual int i) {}   // C2433
