Unused variable $key

Kindly review patch.

The issue summary should always describe what should be fixed/changed. The title is not sufficient to describe what the issue is, even in the case a patch is provided.

(Also, that alone is not a change required by the Drupal coding standards.)

@apaderno,
I believe @Shanu is saying for file - src/controller/EntityUpdateDiffJsonController.php. The foreach loop is having $key variable in its syntax - To which she thinks is unused. Because we are iterating the array values through the $value variable. Basically, we use the $key if we are having data in associative arrays[0],[1],[2].say- for indexing. Thank You.

@Raveen Thakur Still, the issue summary should report what the issue is. That is necessary to understand if the patch/MR is correct and whether the change is proposed for the correct reason.

@Alberto Paderno, yes, agrees.
