DRS4 baseline creation script fails with ctapipe io lst 0.22.2 and EVB5 data

[morcuended]

For DRS4 run 15451 (taken with EVB5)

Error traceback:

For run 15385 (second test night 2023-11-10 with EVB6, only with baseline correction applied). The script seem to work but with a CRITICAL message:

2023-11-13 10:59:08,599 CRITICAL [lstchain.lstchain_create_drs4_pedestal_file] (lstchain_create_drs4_pedestal_file.finish): 8726424 baseline values are smaller than 0

probably related to the baseline subtraction file that was used by EVB?

No, it's a refactoring I did here. Needs a fix here (and a test), the drs4 pedestal script uses the option trigger_information=False, which results in trigger not being filled.
