Description of the Change

TAS 2.13 introduces dynamic asgs feature which automatically updates security-groups for running and staging applications without the need for restart after security-groups were added/updated or removed.

Why Is This PR Valuable?

Users will see the new tip after they run security-groups commands like (bind-security-group, unbind-security-group and update-security-group) that their changes will be applied automatically if they have dynamic asgs enabled.

Why Should This Be In Core?

Because it is currently in core and provides incorrect tip.
