Update the teams description from Skill matrix google sheet

[AleksandarPredic]

The WCEU contributing team will prepare a new document, the skills matrix, for the other issue on this repository. When filling this document, each wp.org team should enter the description for its team which we will use for the last section of the tool.

When we have new descriptions of the teams we need to refactor the file: https://github.com/wceu/contributor-orientation-tool/blob/master/src/src/WPCOTool/config/teams.php

About 2-3 years ago a short description was already found for each team and translated into lots of languages. You can find the original file on e,g, https://translate.wordpress.org/projects/meta/get-involved/fr/default/ It might be an idea to give that as a starting point to all team reps (https://make.wordpress.org/updates/team-reps/) for a review
