NFTShape not working in Decentraland SDK7 Web Editor or Visual Code plugin

[jmseigneur]

Issue Description:

The NFTShape is supposed to display a NFT in a scene easily thanks to the Decentraland Web Editor or Visual Code plugin. However, we have tried with different set up and NFTShape doesn't work. It doesn't display any NFT even NFTs on Ethereum mainnet. It may be due to the fact that there are missing new fields in the NFTShape UI for example there is no contract standard field and only erc721 could be used. Anyway erc721 aren't dispalyed

Steps to reproduce:

1. Add NFTShape in a scene in the Decentraland Web Editor
2. Specify the NFT contract address and number (contract standard cannot be specified because there is no field)
3. Check the scene in preview. No NFT is displayed.

Expected behaviour:

Display an NFT in a scene

Current behaviour:

Not displaying any NFT in a scene
