Python 3.15's importlib.metadata now strictly requires PKG-INFO files
in egg-info directories when accessing the requires property. Without it,
self.metadata is None and triggers AttributeError when reading d.requires.
Although reported as a regression, upstream chose to enforce this requirement
rather than handle missing metadata gracefully.

python/cpython#143387

In near future, it will raise MetadataNotFound(FileNotFoundError).

In Python 3.15, importlib.metadata raises MetadataNotFound
(a FileNotFoundError subclass) when a dist-info directory has no
METADATA file. Previously, it returned None.
