Why

saveCalendarAsync in Expo Calendar checks the permission for calendars even if the passed entity is of type Reminders; it also doesn't check for reminders permissions in this case.

How

Check respective permissions based on entityType in the calendar details payload.

Test Plan

1. With an app set with no calendar permission and only reminders permission, we can't create a reminder list in the Reminders app, getting the error of missing calendar permission.
2. Apply the fix.
3. Now if we are only creating a reminder list without any calendar permission, it can go through without an issue.
