Type of issue

Missing information

Description

The section "The "MMM" custom format specifier" contains the following information:

If there is a "d" or "dd" custom format specifier in the custom format string, it is retrieved from the DateTimeFormatInfo.AbbreviatedMonthGenitiveNames property instead.

It looks like this is only true for .NET 8/9.
.NET Framework 4.8 seems to not do this.
I haven't tested .NET 7 or older versions of .NET Core.

I assume the same is true for the similar note in the section "The "MMMM" custom format specifier", but I haven't tested this.

That notes were added in #40823 by @geniuszxy, although those specific changes were suggested by @tarekgh
