Fix tqdm notebook error in apptainer containers

[ekatralis]

Description

This PR fixes an issue that was introduced in low privilege environments (like lxplus) when using apptainer with IPython 9.13.0

The error originated from a permission issue when importing tqdm.notebook, which seems unnecessary if we are not running from a notebook environment. This fix changes the import logic to avoid errors in simple imports.

This change is important to ensure that cvmfs containers do not crash.
