Replaced [String] dependency url with [Package.Dependency]

[kandelvijaya]

Problem Statement

The problem with [String] urls was that inside the Package specification, we were running a map function that was inserting major version 2 for all the URLS. This is not the best way to deal although we only have 1 dependency at the moment.

Reason:

What if in some near future we add 1 more dependency? Will that dependency also take 2 as major version? Likely not.

Solution:

The current approach adds the ability to add fully satisfied dependency without the explicit knowledge of mapping over.
