Description of what changed

This kind of replace operator was already in Windows PowerShell but was never documented.
<input> <operator> <original>, <substitute>
Here input can be not only scalar but IEnumerable object (an array in simple case). PowerShell will magically convert elements from the object to strings. In PowerShell/PowerShell#14221 this kind of replace operator was optimized for performance and can be efficiently used by users.
