DisplayAttribute string properties: Remarks incorrectly state the property performs resource lookup

### Type of issue

Other (describe below)

### Description

The Remarks section on `ShortName` currently states that *the property* returns the
localized string when `ResourceType` is specified and the value represents a resource key.

That describes `GetShortName()`, not the property. The property getter returns the #raw
value — either a literal string or a resource key — and performs no lookup.

The summary of DisplayAttribute.ShortName that says that ShortName may be a resource key string:

DisplayAttribute.Name docs do highlight that it may be a resource key string and suggest to use GetName() for UI:

Open the DisplayAttribute.xml source and locate the documentation for the ShortName property. Compare its Remarks with the Name documentation and the distinction between the property and GetShortName(). Done means the ShortName docs accurately describe the raw value and do not say that the property performs resource lookup.
