Find and Tag/Correct Duplicate shadows [Always open]

[nakulrathore]

some shadows (shadow values) are duplicates, see ex: "Instagram login box",
(if you don't find example, its probably removed )

verify and correct those shadow values by going to that website(in this example checking out instagram login box),

or

tag the duplicate shadow in shadow.js file with key "duplicateOf"

example

 {
    name: "Example shadow",
   duplicateOf : 'Original shadow name',
    shadow: "0 2px 2px 0 rgba(0,0,0,0.14)",
    border: "0"
  },

DONT remove that shadow, just tag or update it, make sure to provide a description of the action you took in the pull request.

commits referring this issue will be reviewed before we make any changes.
