fix: Update debian_build.yml distro from questing to resolute

The matrix definition referenced 'questing' but the include section only had
mappings for 'jammy', 'noble', and 'resolute'. This mismatch caused GitHub
Actions workflow validation to fail (Job 24348685207). Now both the matrix
and include section consistently use resolute for Ubuntu 26.04.
