Publishing to PYPI fails with InvalidDistribution

[ritchie46]

Bug Description

The Polars release failed (twice) with:

Checking dist/polars-1.16.0-cp39-abi3-macosx_10_12_x86_64.whl: ERROR    InvalidDistribution: Metadata is missing required fields: Name, Version.                                                               
         Make sure the distribution includes the files where those fields are   
         specified, and is using a supported Metadata-Version: 1.0, 1.1, 1.2,   
         2.0, 2.1, 2.2, 2.3.

Your maturin version (maturin --version)

latest (1.7.6)

Your Python version (python -V)

Your pip version (pip -V)

What bindings you're using

pyo3

Does cargo build work?

• Yes, it works

If on windows, have you checked that you aren't accidentally using unix path (those with the forward slash /)?

• Yes

Steps to Reproduce

[messense]

Duplicate of #2335, same underlying issue with twine not supporting metadata version 2.4 yet.

Consider use maturin 1.7.4 if you don't need to build for python3.13t free-threaded version.
