collectionDetails on CreateMetadataAccountV3Data is an enum type

[4xMafole]

Describe the bug
On our package, I can see that the collectionDetails parameter is a bool type. Meanwhile, on the Metaplex documentation says this field is an enum.
"The CollectionDetails is an optional enum which currently contains only one option V1. This option is a struct that contains the following field:
Size: The size of the collection, i.e. the number of NFTs that are directly linked to this Collection NFT. This number is automatically computed by the Token Metadata program but can also be set manually to facilitate the migration process." - Metaplex Documentation

To Reproduce
Steps to reproduce the behavior:

1. Create a metadata account data and set collectionDetails = true.
   e.g:

   final dataMetadataCollection = CreateMetadataAccountV3Data(
      name: nftData.name,
      symbol: nftData.symbol,
      uri: nftData.dataUri,
      sellerFeeBasisPoints: 500,
      isMutable: true,
      colectionDetails: true, //Here is the field
      creators: [
        MetadataCreator(
          address: owner.publicKey,
          verified: true,
          share: 100,
        ),
      ],
    );

Expected behavior
To create a collection NFT differentiating it from normal NFT using collectionDetails field.
