run_number_from_filename does not work for CORSIKA log files

The function run_number_from_filename in the following

https://gitlab.cta-observatory.org/cta-computing/dpps/workload/CTADIRAC/-/blob/main/src/CTADIRAC/Core/Utilities/tool_box.py?ref_type=heads#L68

does not recognise the run number of CORSIKA log files. Not critical, but should be fixed.
