Change names of Docs Versions

[edwingamboa]

AS-IS

Currently, the documentation is divided into 2 versions, one for "RTE 2x" and another one for "RTE3x". However, the docs are divided because of modelVersion (10.x and 10.1x).In fact, both versions use RTE 3x.

TO-BE

Docs should be named based on modelVersion -> Model Version <= 10.0.0 and Model Version >= 10.1.0

Now links are:

• Docs for Docs for Model Version >= 10.1.0: http://cubbles.github.io/docs/
• Docs for Model Version <= 10.0.0: http://cubbles.github.io/docs_10/
