Adding 'Copy to clipboard' buttons into the Command line instructions after creating a blank new project

Enhancement discussed with @stingrayza during our monthly feedback meeting.

Context

When creating a new repository and unticking 'Initialize repository with a README' checkbox, you arrive on the newly created page. In this page there is a section called 'Command line instructions', in this section it would be nice to add the feature allowing the user to easily copy/paste the code instructions
