[OC-7791] Tokenization - Updated deserialization for stricter parsing

[trongvnau]

Pull Request Description

Deserializer for TokenLinkDtoTokenMetadata is not strict enough and pick up all 3 subtypes: AssetMetadataDto, CollectionMetadataDto and ContractMetadataDto and throws an exception even though for example the json is for AssetMetadataDto and has only properties that belong to AssetMetadataDto

Example SDK call TokenLinkDto data = fireblocks.tokenization().getLinkedToken(idToken).join().getData();

Exception thrown

java.util.concurrent.CompletionException: com.fireblocks.sdk.ApiException: com.fasterxml.jackson.databind.JsonMappingException: Unexpected IOException (of type java.io.IOException): Failed deserialization for TokenLinkDtoTokenMetadata: 3 classes match result, expected 1
