[I18N] migrate to the nex transifex API

Tansifex is deprecating it's client and switches to a go-based
solution in its API v3

The new client is still backward compatible with the old format but
the v2 API is going to be phased out.
See https://github.com/transifex/cli to install the deplyments using
the tx client

This PR is the result of the "tx migrate" command
