Pin macOS wheel target to 13.0 in release and nightly workflows (#10054)

Browse source 
Wheels started inheriting `macosx_15_0` tags because macOS jobs run on
newer runners and no deployment target was pinned. That blocks wheel
installation on macOS 13/14 hosts and forces source builds.

- **macOS deployment target pinning**
- Added `MACOSX_DEPLOYMENT_TARGET: "13.0"` to both macOS build jobs
(`x64`, `arm64`) in:
    - `.github/workflows/release.yml`
    - `.github/workflows/nightly.yml`

- **Stable macOS artifact OS metadata**
- Updated macOS `mk_unix_dist.py` invocations to pass `--os=osx-13.0` in
both workflows, so artifact metadata stays aligned with the intended
minimum macOS compatibility used for Python wheel tagging.

```yaml
mac-build-x64:
  runs-on: macos-15
  env:
    MACOSX_DEPLOYMENT_TARGET: "13.0"
  steps:
    - name: Build
      run: python scripts/mk_unix_dist.py --dotnet-key=$GITHUB_WORKSPACE/resources/z3.snk --arch=x64 --os=osx-13.0
```
