Debos build output hidden on GitLab job view can only be seen in the raw log file

Affected images versions

• The apertis/v2022 branch is already affected (apt 2.2.4, Bullseye).

Unaffected images versions

• Builds on the apertis/v2021 branch were not affected (apt 1.8.2, Buster).

Steps to reproduce

• Trigger a new infrastructure/apertis-image-recipes> pipeline

Expected result

All the output from Debos/APT can be seen in the job view

Actual result

Some portions of the output are not shown in the job view and can only be seen in the raw log.

For instance, in the job view:

2023/02/15 05:39:28 ==== Core packages ====
2023/02/15 05:39:36 ==== Base packages ====

And in the raw log:

Reproducibility

1. ✅ always
2. often, but not always
3. rarely

Impact of bug

Just an annoyance since the full output is in the raw log, but periodically someone spends a a few hours confused before getting pointed to the raw log by some other teammate.

Root cause

describe in one line what caused the issue to give a hint to product teams whether they may be impacted or not

Outcomes

TBD

Management data

This section is for management only, it should be the last one in the description.
