ci: QoS matching on Humble does not work in CI

[maciejmajek]

Describe the bug
For some reason, the CI (pytest) fails on tests/messages/test_transport.py (introduced in #353) fails on ROS 2 Humble. Problem could not be reproduced on two different Ubuntu 22.04 systems (one used, one fresh).

To Reproduce
Create a new branch, revert a0779e5, create PR to run CI.

Expected behavior
The test should pass the same way it passes on standard systems.

Platform

• OS: Ubuntu 22.04
• ROS 2 Humble

Version
#353

Additional context
None
