I noticed a few issues in CI.yml:

• Currently, GitHub Actions' macos-latest (and macos-14) default to machines with Apple Silicon (aarch64, M1/M2) chipsets.
• Compilation for S390 failed because the env:CFLAGS_s390x_unknown_linux_gnu: -march=z10 flag was missing. See: psm fails to cross compile to S390x#79

So I ran the GitHub Actions again using maturin generate-ci github and added CFLAGS_s390x_unknown_linux_gnu: -march=z10. It worked fine.

If you think it's ok, I will update the following ci.yml ?

@un4gt that sounds good go ahead
