[Jackson 3] `MonthSerializer` should follow regular `serializer` not as plain `Enum` class.

[JooHyukKim]

Is your feature request related to a problem? Please describe.

Currently java.time.Months MonthSerializer treats Month's as plain Enum. While implementation would be simple that way, it cannot or make difficult to leverage more robust features like JsonFormat shape overrides, and DateTimeFeatures.

Describe the solution you'd like

Remove Enum handling from java.time.Months MonthSerializer and do like MonthDayDeserializer?

Added PR #5128 to discuss how it should behave

Thanks again @JooHyukKim !

[JooHyukKim]

@cowtowncoder Any idea on where and how to document this behavior change? 🤔
I am trying to figure out when user comes to report breaking behavior, what to tell that person?

[cowtowncoder]

@JooHyukKim Yeah that is the question. I am not quite sure. One possibility would be to add this to:

Makes sense, added to JSTEP-2
