Actually add Py_3_14 as a legitimate macro

clin1234 · clin1234 · commit 5da57afaee19 · 2025-01-23T10:30:40.000-05:00
When `rustc` is invoked, the macro is included with the `--check-cfg`
flag, but not with the `--cfg` flag. This caused errors about duplicate
definitions to spew out when building with stable Rust toolchains.
