MDEV-27033: Remove version suffix from Debian packages
Remove version suffix from Debian packages (for example mariadb-server-10.9) because installing suffixed package removes older version of package even if it's suffixed (for example mariadb-server-10.7) This make also Debian package management easier in future MariaDB version iterations because there is no need for stacking Conlicts/Breaks/Replaces-parameters in every new major release
