core: Local calendar: another start/end validation error

The problem

Hi, already found the other validation error that should have been fixed by https://github.com/home-assistant/core/pull/84104 However, after upgrading to 2022.12.7, my calendar still disappears after a restart.

There is only one entry in the calendar, repeating for ever, with a weekly schedule of Monday to Friday.

Log:
