EnumType is not documented as new in 3.11

Documentation

In python 3.10 and earlier Enum's metaclass was called EnumMeta. https://docs.python.org/3.10/library/enum.html#enum-classes
In python 3.11 this was renamed EnumType (https://docs.python.org/3.11/whatsnew/3.11.html#enum).
However the fact that EnumType was introduced in Python 3.11 is not mentioned. https://docs.python.org/3.10/library/enum.html#enum-classes
Nor is the fact that EnumMeta still exists as an alias.

This would be useful to document.

Looks like EnumType is documented: https://docs.python.org/3.11/library/enum.html#enum.EnumType

@sobolevn -- I think the point is more that a .. versionadded:: 3.11 directive is missing.
