Ensure project short tag used in notebook tests

[ckunki]

Make AI-Lab notebook tests use environment variable PROJECT_SHORT_TAG=XAIL-NB in nbtest_environ when running the tests for a jupyter notebook in test_notebook() in notebook_test_runner, see details at pytest-exasol-backend.

Details

1. Set environment variable PROJECT_SHORT_TAG=XAIL-NB in GitHub workflow notebook_tests.yaml
2. Copy environment variable into nbtest_environ.

Background

An increasing number of projects are starting up instances of Exasol SaaS database for running integration tests. In case of failures leaving behind running database instances and hence causing costs, we want to know which project did start the resp. database instance.

Currently, the database instances are only labeled with a timestamp and the user jupyter which is not very descriptive.

I needed to update ca-certificates to 20240203~22.04.1 as the formerly used version 20230311ubuntu0.22.04.1 was no longer available.

Here is the output of sudo apt update; sudo apt search ca-certificates:

ca-certificates/jammy-updates,jammy-security 20240203~22.04.1 all [upgradable from: 20230311ubuntu0.22.04.1]
