BULL-1202 | Added pipeline name to the data sent to the frontend

I have updated the project-service.js file to send a request to Gitlab's API to retrieve the name of the desired pipeline in order to send it to the frontend. Doing so will allow us to match the design here for project cards: https://www.figma.com/file/WGrO0RhQROrJkTHxe7HOFi/P1-Launchboard?node-id=2478%3A0 .

This merge request must be merged in parallel with the Launchboard-fe merge request: launchboard-fe!143 (merged)
