Invalid contracts generated for @openzeppelin/contracts 4.9.0

[annamcallister]

The wizard no longer works with all options when @openzeppelin/contracts is installed at v4.9.0, which is the latest version published to npm as of yesterday.

e.g. when URI Storage is chosen for ERC721, you get this compilation error.

Derived contract must override function \"supportsInterface\". Two or more base classes define function with same name and parameter types.\n --> contract.sol:8:1:\n |\n8 | contract Token is ERC721, ERC721URIStorage, Ownable {\n | ^ (Relevant source part starts here and spans across multiple lines).\nNote: Definition in \"ERC721\": \n --> @openzeppelin/contracts/token/ERC721/ERC721.sol:52:5:\n |\n52 | function supportsInterface(bytes4 interfaceId) public view virtual override(ERC165, IERC165) returns (bool) {\n | ^ (Relevant source part starts here and spans across multiple lines).\nNote: Definition in \"ERC721URIStorage\": \n --> @openzeppelin/contracts/token/ERC721/extensions/ERC721URIStorage.sol:21:5:\n |\n21 | function supportsInterface(bytes4 interfaceId) public view virtual override(ERC721, IERC165) returns (bool) {\n | ^ (Relevant source part starts here and spans across multiple lines).\n\n","message":"Derived contract must override function \"supportsInterface\".
