Let chantal only clone the needed branch

[TheJJ]

Currently, the whole repo is cloned for a job. If the repo has many branches and unneccessary stuff, the clone takes quite some time and traffic, even though the needed branch may be much smaller.

-> Update the git clone call to only fetch the needed commit (and its ancestors).
