Update Address Validation and Metadata Descriptions in Contracts

- Modified the address validation method in `Erc721EthscriptionsCollectionParser` to be case-insensitive for Ethereum addresses.
- Updated the description in the `NameRegistry` contract to clarify the purpose of the Ethscriptions name and allowed characters.
- Enhanced metadata attributes to include the length of the name, improving the representation of domain characteristics.
