[Documention] RSA_AES_KEY_WRAP_SHA_256 wrapping/unwraping (2 steps)

[HatemMn]

This isn't a bug - rather a request reminder for documentation

While the KMS is able to do this operation, it lacks documentation on the matter

Docs can be added here : https://docs.cosmian.com/key_management_system/kmip/_export/

To acheive that hybird unwrapping scheme, we should provide :

CryptographicParameters {
                cryptographic_algorithm: Some(CryptographicAlgorithm::RSA),
                // Note: We use "None" padding to route toward RSA AES Key Wrap, this is not a mistake
                // see: crate/crypto/src/crypto/wrap/unwrap_key.rs line 365
                padding_method: Some(PaddingMethod::None),
                hashing_algorithm: Some(HashingAlgorithm::SHA1),
                ..CryptographicParameters::default()
            },

Since counter-intuitive, this behavior is better to be documented (don't take this issue, I will do it. Ping me if something is not clear)
