Days shifted after changing "Start week on:" (fixed after reload/restart)

Describe the bug

When changing the "Start week on" option, the days of the week will be shifted by one. Restarting or reloading Obsidian fixes the issue.

Steps to reproduce

1. In the calendar, navigate to January 2022. Note that January 1 is a Saturday.
2. Go to Settings -> Calendar
3. Change the 'Start week on' option ie. from Monday to Sunday
4. Error: The days of the week are shifted by one. January 1 now appears to start on Friday.
5. Reloading (or restarting) obsidian fixes that. The year starts on Saturday again.

Note that I'm using 'de' as my locale.

Expected behavior

The calendar should change immediately without restarting or reloading obsidian.

Screenshots

Apple Calendar as a reference: January 1 is a Saturday

Initial situation (locale: de, start week on locale default (mondays)): January 1 is a Saturday (correct)

Changing 'Start week on' to Sunday ('Sonntag'): January 1 appears to be a Friday (wrong)
