Update Deployment of Sleeper CLI Documentation

[ab295382]

Background

Caused by:

• Sleeper CLI Docker images on main branch can't be pulled #2494

Description

The Sleeper CLI deployment needs to be update to inform users that they must use the develop branch for its deployment. This is because Github thinks the containers are there but they cannot be pulled. This is the case for main and the released versions therefore update docs/01-getting-started.md to inform users of the current issue.

Analysis

We can either change the install script to default to pull from develop for now, or we can just have the documentation explain the problem and tell users to explicitly install the develop version. If we do the latter, people may still just run the install script with no parameters. It wouldn't work as that currently defaults to pull the latest release version.
