fix possible misunderstanding (Return value of Current property and Entry property at IDictionaryEnumerator Interface) (#2203)

* fix possible misunderstanding

Return value of Current property and Entry property isn't fully similar.
As variant it can be written as "the return value of the Entry property (is an unboxed DictionaryEntry)" or (is an unboxed value of Current property).

* Feedback

* Update IDictionaryEnumerator.xml
