Use the new ritchie-templates repository with rit init command

[GuillaumeFalourd]

What would you like to be added:

• The rit init command should now add the ritchie-templates repository (https://github.com/ZupIT/ritchie-templates) instead of the commons repository (https://github.com/ZupIT/ritchie-formulas).

Note: Don't remove the templates from the ritchie-formulas repository, as they will be needed for older versions.

Why is this needed:

• Today, Ritchie users have to add ZupIT formulas locally to be able to create formulas, which doesn't make sense as the objective of the tool is to allow anyone to customize formulas and automations they want to use locally.
• Moreover, we plan to add new templates soon for each languages, to allow users to choose between templates that may already abstract part of the code implementation needed (Consuming API, Empty, Hello World, and so on...)

Note: It is currently not possible to add repositories without formulas with the add repo command. In that case, I suggest to use a bypass if the repo added is this specific ritchie-templates one. The related method that perform this check is this one.
