Use a more verbose CI changelog message for debian
This MR patches the Debian CI pipeline to use a longer message when calling dch, so that lintian doesn't pedantically complain, it just adds noise.
Maintenance will be performed on git.ligo.org, containers.ligo.org, and docs.ligo.org on Tuesday 10 February 2026 starting at approximately 900 MST (1600 UTC). It is expected to take around 30 minutes and there will be several periods of downtime throughout the maintenance. Please address any comments, concerns, or questions to the helpdesk.
