Internationalization doc mentions deprecated transifex-client

[rffontenelle]

Describe the bug

In the Internationalization page, the Using Transifex service for team translation section tells to use the Python-based transifex-client, however it is deprecated. Quoting the info on the new tool:

Please start using the new Transifex CLI here , since this software is considered deprecated (as of January 2022) and will sunset on Nov 30, 2022.

The new Transifex tool is written in Go, commonly named "Transifex CLI tool" , that has almost the same options (tx pull, tx push, etc.) and has the same binary name tx. The installation and usage instructions can be found in the documentation (https://developers.transifex.com/docs/cli) and source code repository (https://github.com/transifex/cli)

The section needs to be updated with this information.
