DiffInMonths does not consider the positive and negative of the time period

[almas1992]

Hello,

I encountered an issue with the following code:

carbon.Parse("2022-08-08 22:55:15").DiffInMonths(carbon.Parse("2022-09-18 22:55:19"))
carbon.Parse("2022-09-18 22:55:19").DiffInMonths(carbon.Parse("2022-08-08 22:55:15"))

golang version: sgo1.19.1 darwin/arm64

carbon version: v2.1.9

time zone: such as Japan

I expected to get:

1
-1

But I actually get:

1
-2

Thanks!
