No show_attribute options on AssetParams types

[Wildanzr]

I noticed there is a bit of a difference in the NFTScan API, especially in the Solana API docs. There were options for show_attributes with types boolean on every Retrieve Assets API, but this property seems not to exist in the AssetParams types and only exists in QueryAssetsByCollectionParams. The problem is that QueryAssetsByCollectionParams is not being used for every Retrieve Assets API, so some functions don't have it.
