doc: Document additional parametrization of serializers `#[near(serializers=[borsh(…), json(…)])]`

[frol]

#1158 Implementation is not documented and as such is not discoverable

Let’s extend the reference documentation https://docs.rs/near-sdk/latest/near_sdk/attr.near.html#nearserializers-annotates-structsenums

Could I be assigned to this?

[frol]

@Manuelshub sure, you are welcome. Just note that extra parameters are only supported for borsh, but not json, so you may either document this behavior and suggest to use #[serde(…)] explicitly, or add the support for serde params passed via json element of the list and document both borsh and serde the same way

@frol Hey thanks, would it be possible to get more context regarding this issue.

[Manuelshub]

@frol Most of the changes from the #1158 is not reflecting in the Master branch, please I'll need you to look into it. Thank you.
