Adjust "nuke-graph-directory.sh" shebang to be explicitly Bash (includes a Bashism as of https://github.com/docker/docker/pull/27869) Upstream-commit: 6d1937aa2d803e10124eea5ef68e2e4f89d3b4b3 Component: engine
The contrib directory contains scripts, images, and other helpful things
which are not part of the core docker distribution. Please note that they
could be out of date, since they do not receive the same attention as the
rest of the repository.
