Cython3 chokes on astropy 5.3.3 (worked in 5.3.2)

### Description

For the openSUSE Tumbleweed rpm package, we have been ignoring the exact version pin for Cython

https://github.com/astropy/astropy/blob/6258f070b71ab42cc6efd4a99345f332ff44ca98/pyproject.toml#L4

... and ran into a test failure possibly related to #15076 and #15049

Restraining the build to Cython < 3 helped us.

### Expected behavior

Passing test suite

### How to Reproduce

1. Build astropy 5.3.3 with Cython 3
2. Run tests

```python
import astropy
astropy.test(args="-k w0wzCDM")
```
