fix(ng-dev/pr): Use --deepen in place of --depth during fetches i…

…n rebasing

Previously we used `--depth` to ensure that enough commits were included in the repository to effectively
perform rebases.  However, using `--depth` sets the depth of the repository, and if the repository previously
was unshallow, it because a shallow repository.  Instead by using deepen, the depth will be increased by the
provided value.  This will ensure that the enough commits are included and will be a noop if an unshallow
repo is deepened further.
