Add kind to all interaction enum variants to fix interaction serde

[cheesycod]

Currently, serializing an Interaction strips its type entirely making said interaction not only not deserializable but also need manual patching to confirm with discords own JSON structure (e.g. when serializing it for storage/use in other systems, the resulting JSON loses the type entirely)

Fix this issue the same way Components are implemented: by adding a kind to each interaction variant.

So this just increases model sizes... for what? The struct is the kind of interaction and there isn't really a reason to serialize these types? Not even sure why they even implement serialize tbh

Right now, i have to manually inject type into Interaction before serializing them into serde_json::Value (and finally mlua::LuaValue (at the end of the day) and dumping it there. I actually rely heavily on the fact that you can serialize interactions throughout my bot

E.g:

                    // Inject in type
                    if let serde_json::Value::Object(ref mut map) = value {
                        let typ: u8 = interaction.kind().0;
                        map.insert("type".to_string(), serde_json::Value::Number(typ.into()));
                    }

                    serde_json::json!({
                        "InteractionCreate": {
                            "interaction": value
                        }
                    })
