Correct CI fitter

[wenceslas-sanchez]

Reference to #4 where the github action failed. Here is what I did to correct it :

• delete .yml file
• run locally npx prettier --write . then commit/push
• re add the .yml file

I faced the same issue and that procedure works. 😄

As you can see, github action works here 😃
