Make the --suffix argument optional in the release workflow, and add a --platform all option

[agriyakhetarpal]

After #22, wheels failed as the --suffix argument is always supplied to the wheel generation command when it is optional. This PR fixes it.

Tested on my fork, all good: https://github.com/agriyakhetarpal/zig-pypi/actions/runs/17711708847/job/50331241037

I think one improvement we can make here is to deduplicate the platforms to build the wheels for, as we currently require both make_wheels.py and the workflow file to be updated, which could easily be missed.

Yup that would be great. --platform all?

[agriyakhetarpal]

Even better! On it.

I've tested on my fork as follows.

1. with a specific platform (aarch64-macos): https://github.com/agriyakhetarpal/zig-pypi/actions/runs/17711933957
2. with all platforms: https://github.com/agriyakhetarpal/zig-pypi/actions/runs/17711974638

Both of these have no suffixes.

[agriyakhetarpal]

Is this better?

[agriyakhetarpal]

The workflow now runs well with default values (all platforms, latest stable release, no suffixes): https://github.com/agriyakhetarpal/zig-pypi/actions/runs/17712015516/job/50331918315.
