Issue when starting the building container tdp-builder

[Yanis77240]

When running the script ./bin/start-build-env.sh, I got an error stating that the gid I am using to create the builder user in the container already exists. This is due to the fact that in the distro that I am using (NixOS), the gid of my user is 100 which is the same gid as the group users in the container.

There is no immediate solution to resolve this specific it's the ubuntu base that defines this group in the dockerfile.

There is very little chance that we're going to fix this.

The only workaround available for the moment would be to create a group with specific gid, but note that you should be able to use any GID that shouldn't be a problem

Settings GID=1000 should work, even if it does not exist.

It would be nice to mention this in the doc at the right place.
