We have added workers to playwright to run tests in parallel,
this will help us to run tests faster.
The tests run on a commun database, so to keep the tests
stable between browsers, we created 3 different
users to run the tests, it will avoid to have commun data
stepping on each other.
We need to add a linter to the i18n package, we are mainly
interested by the jest linting rules so we create
a jest eslint config pluggable our other configs and to the
i18n eslint config.
