MNT: fix missing build-backend key in pyproject.toml

rgommers · rdbisme · commit bf18fd5044dc · 2025-05-12T02:03:29.000+02:00
This is a clear bug, `setuptools` only accepts having a `build-requires`
section but no `build-backend` key either accidentally or for historical
reasons, and will stop doing so at some point.
