Use Phrase/phrase instead of PhraseApp/phraseapp/phrase_app everywhere

[junan]

Why

PhraseApp now is Phrase. They not only changed the software/company name they also changed their CLI/configuration in the latest version where we have to use phrase instead phraseapp.

Here is a list of changes they did

• Software/Company name changed PhraseApp to Phrase
• They deprecated CLI v1(cli command start with phraseapp, we use it for our all rails project)
• They introduced CLI v2 where we have to use phrase CLI command instead of phraseapp and translation config file name will be .phrase.yml instead of .phraseapp.yml

So we should update rails-template so it use for Phrase CLI v2 and refer everywhere as Phrase/phrase instead of PhraseApp/phraseapp/phrase_app. And update it we mostly need to rename.(.phraseapp.yml => .phrase.yml, PhraseApp/phraseapp/phrase_app => Phrase/phrase)

Who Benefits?

Everyone who will use rails-template as it refer correct Phrase software name and will use Phrase recommenced CLI v2
