Upgrade to release 4.0.4:
- Raise DNSError(ARES_ENODATA) from query() when the answer section
has no records of the requested qtype, restoring the pycares 4.x
NODATA contract and avoiding AttributeError for CNAME/SOA/PTR callers
- Add the missing build-backend entry to pyproject.toml so PEP 517
builds from the sdist work without falling back to the deprecated
legacy setuptools backend
