Scheduler recurrence editor "until" rule with timezone

[kirchoni]

The scheduler component does not work correctly when using the until field with and a timezone is being set.

Steps to reproduce:

1. Open this stackblitz example
2. Set your system's timezone to something that isn't UTC+0 ("Cheturnal (UTC-5)" and "West Central Africa (UTC+1)" used as examples)
3. Ensure the timezone of the scheduler to 'Etc/UTC'.
4. Begin making an event at 1 AM on 6/19/2022.
5. Have the event repeat daily, ending on 6/22/2022 by picking that day in the date picker.
6. Save the event.
7. Repeat the last 4 steps by making an event at 11 PM.

Notes: It seems the until datepicker picks the timepart before converting to the corresponding timezone.
