CalendarYearMonthFromFields:
1. Perform ? CalendarResolveFields(_calendar_, _fields_, ~year-month~).
2. Let _firstDayIndex_ be the 1-based index of the first day of the month
described by _fields_ (i.e., 1 unless the month's first day is skipped by
this calendar.)
3. Set _fields_.[[Day]] to _firstDayIndex_.
4. Let result be ? CalendarDateToISO(_calendar_, _fields_, _overflow_).
CalendarResolveFields:
When the fields of _fields_ are inconsistent with respect to a non-unset
_fields_.[[Era]], it is recommended that _fields_.[[Era]] and
_fields_.[[EraYear]] be updated to resolve the inconsistency by lenient
interpretation of out-of-bounds values (rather than throwing a *RangeError*),
which is particularly useful for consistent interpretation of dates in
calendars with regnal eras.
