[AugustinMauroy]

translation of "getting started" in French

• need preview
• need review @nodejs/nodejs-fr

Check List

• I have read the Contributing Guidelines and made commit messages that follow the guideline.
• I have run npm run lint:js -- --fix and/or npm run lint:md -- --fix for my JavaScript and/or Markdown changes.
• This is important as most of the cases your code changes might not be correctly linted
• I have run npm run test to check if all tests are passing, and/or npm run test -- -u to update snapshots if I created and/or updated React Components.
• I have checked that the build works locally and that npm run build work fine.
• I've covered new added functionality with unit tests if necessary.
