Remove legacy word-domains protocol support and associated parser

- Deleted the `WordDomainsParser` class and its references from the `ProtocolParser`, streamlining protocol handling.
- Removed the `name_registry` contract and its related tests, eliminating legacy word-domain registration functionality.
- Updated the `L2Genesis` contract to exclude the `NameRegistry` from proxied contract checks and registration.
- Adjusted tests to reflect the removal of word-domains, ensuring consistency across the codebase.
