aptly: add gomemlimit var in Development

The Aptly service is currently running with excess memory, which needs to be limited to prevent it from consuming all available node memory. To achieve this, we must introduce an environment variable to the container. By setting this variable, Aptly will be restricted to using a maximum of GB of memory.

Upgrade Aptly to the latest version to incorporate this new feature.
