Fix test_singularity_container_test test

(which started failing since ubuntu-latest was moved to 24.04)
by upgrading apptainer to >=1.3.3 to include
apptainer/apptainer#2262 .

Fix:

```
>       assert "samtools:1.0--1" in results["passed"], results

- Improve assertion messages to facilitate debugging
