Update from debian/bookworm for apertis/v2024dev3

debian/changelog

+apt (2.6.1+apertis1) apertis; urgency=medium
+
+  * Sync updates from debian/bookworm
+  * Remaining Apertis specific changes:
+    - Fix error handling with getline
+      The function getline is used to read data from different streams, however,
+      the error handling is not accurate. Check both return value and errno
+      to handle errors.
+    - Add sequoia-gpgv dependency
+    - Add Apertis vendor configuration.

+apt (2.6.1) unstable; urgency=medium
+
+  * Restore adduser dependency for bookworm.
+    This caused some regressions to late in the bookworm cycle. To keep
+    upgrade paths (which will have adduser installed) the same, we drop
+    the base-password alternative rather than requiring both dependencies,
+    as that could change resolving or ordering bugs. (Closes: #1035654)
+  * Point gitlab-ci and gbp to bookworm/2.6.y
