Fizz does not work with generic structs

[LorenzoWF]

With the 1.18 version of Go, we can have this:

type MyStruct[T ObjA | ObjB] struct {
    Result T `json:"result"`
}

But unfortunately the fizz cannot generate the spec for this :(

Indeed, the reflect part of the code has not been updated to work with generic code introduced by Go1.18. I might work on it at some point (really depends if there's a need for projects at OVH), but otherwise I would be happy to accept contributions.

Ok, probably i will be send a PR or a draft ideia here 👍 .

Changes made to fizz should be made to tonic first, since the former depends on the latter to work.
I'd need to document myself on the reflect package changes introduced by the addition of generics to get a better understanding of how it can be done.

I'd like to help out. @LorenzoWF did you manage to get to a draft?
