Drop support for macOS 10.12 from wheel build.

[kevinhartman]

Summary

We'd originally expected to build wheels for x86_64 macOS 10.12 in #13470, but it turns out that macOS 13 cannot build anything older than 10.13:

The automatic bump-up to 11 on ARM is presumably something we expect. Correct me if I'm wrong.

Details and comments

This was noticed during the release of Qiskit 1.3.1.

Oddly, the wheel built for macOS ARM uses the bumped-up version of 11:

https://pypi.org/project/qiskit/#qiskit-1.3.1-cp39-abi3-macosx_11_0_arm64.whl

But the x86_64 wheel uses the version 10.12 (even though supposedly it would've been built for 10.13). I'm not sure what will happen, then, if this wheel gets pulled on macOS 10.12. Unfortunately, the included release note should be present in the 1.3.1 release, but is not. Perhaps we can add it manually.

There's a bit more info on why this happens here: #13503 (comment).

@jakelishman thanks! Any idea why the wheel itself built with the 10.13 target still comes out as 10.12+ compatible? Will that actually work if someone running 10.12 pulls it down?

[jakelishman]

I don't, unfortunately - it probably just still happens to only choose APIs that were still present in 10.12. Given that we have very little interaction with the OS from our extension modules, I wouldn't be surprised if our exposure is mostly just limited to the particular formats / initialisation routines in the dynamic libraries, and it's unlikely that macOS 10.13 completely overhauled everything, I guess?

[jakelishman]

Or of course, it's not actually compatible with 10.12, and the audit tool just doesn't catch it.
