[TYPO3-core] FYI #17070: Bug: Scheduler: BE module does not use new cron parser

Hi,

I should add that this is not the only benefit:

- cron syntax checking is more strict, e.g. out of bound values are 
detected, as well as invalid ranges, etc.
- exceptions raised by the cron normalizer class are passed into the 
validation error message, which thus becomes more informative.

Cheers
