fix: support ARM64 architecture in macOS PyPI release script

Detect macOS architecture (arm64 vs x86_64) and download the appropriate
Miniconda version:
- ARM64 (Apple Silicon): Miniconda3-latest-MacOSX-arm64.sh
- x86_64 (Intel): Miniconda3-latest-MacOSX-x86_64.sh

This ensures compatibility with both macos-latest (x86_64) and macos-14 (ARM64)
GitHub Actions runners.
