While we directed the docker image to translate the URLs to https anyway
this can be confusing since git behaves differently in docker vs outside.

Also in the meantime we have made all repos public, so there is no auth needed
for the repos and the extra work required using https no longer applies.

Otherwise this depends on the core bundle image and we don't want that image
to become public API.

We have switched to composer 2 everywhere and while 1.x should still work
we don't test with it. So install composer 2 in the docker image.

So it doesn't default to the directory name and clashes with other
projects.

No need to duplicate this everywhere
