Script in other repository to install pre-published Docker tools

We have a separate repository where we pre-publish versions of Sleeper, and another repository with a script to install Sleeper.

Next to the script to install Sleeper, we'd like another script to install the Docker tools with the pre-published version.

Start by locating the existing Sleeper installation script in the separate repository and reviewing how the pre-published versions are referenced. Add the adjacent script for installing the Docker tools at a pre-published version, then verify that the script completes successfully.
