fix: ABI generation

[mitinarseny]

This PR fixes an issue when ABI generation fails due to absence of #[derive(JsonSchema)]

cargo near build

Basically, in order to properly handle ABI generation via cargo near, you're literally forced to use #[near(serializers = [json])], as its expanded version depends on near-sdk/abi feature, so you can think of expanded version as:

#[derive(::near_sdk::serde::Deserialize, ::near_sdk::serde::Serialize)]
#[serde(crate = "::near_sdk::serde")]
#[cfg_attr(all(feature = "near_sdk/abi", not(target_arch = "wasm32")), derive(::near_sdk::schemars::JsonSchema))]
#[cfg_attr(all(feature = "near_sdk/abi", not(target_arch = "wasm32")), schemars(crate = "::near_sdk::schemars"))]

Maybe other types should be reworked as well?

As I checked, these are the only types exposed in ABI. All other custom types in this crate are needed for events, which are not included in ABI
