Update wheel build and test workflow

[michaeltryby]

This pull request updates the build and test workflows to improve compatibility with newer Python versions and macOS environments, and to streamline artifact handling. The most important changes are grouped below by theme.

Python and GitHub Actions Version Updates:

• Upgraded actions/checkout and actions/setup-python to use version 5 in all workflows for improved reliability and future compatibility. [1] [2]
• Added support for Python 3.13 (cp313) in wheel builds and cross-wheel builds, while removing support for Python 3.8 (cp38). [1] [2] [3]

macOS Build Environment Improvements:

• Set MACOSX_DEPLOYMENT_TARGET to "11.0" in both wheel and unit test workflows to ensure compatibility with newer macOS versions. [1] [2]
• Removed explicit deployment target from CMake arguments for macOS builds in setup.py, relying on environment configuration instead.

Build Matrix and Architecture Updates:

• Expanded macOS build architectures to include both x86_64 and arm64 for broader compatibility, and updated artifact naming for clarity.
• Updated Linux and macOS architecture and skip lists to streamline builds and avoid unnecessary configurations. [1] [2]

Artifact Upload and Naming Improvements:

• Improved artifact upload steps by adding descriptive names to wheel artifacts for easier identification and management. [1] [2] [3]

General Workflow Streamlining:

• Simplified workflow configuration by removing unused or redundant options, such as the os matrix in cross-wheel builds.

These updates help ensure the project is ready for newer Python and macOS releases, improve CI reliability, and make build artifacts easier to manage.

The checkout action is missing the submodules: true configuration that was present in the original version. This could cause build failures if the project depends on git submodules.

Suggested change

There's an extra space after 'name:' in the artifact name. Should be name: wheels-linux-aarch64-${{ matrix.pyver }}

Suggested change

	name: wheels-linux-aarch64-${{ matrix.pyver }}
	name: wheels-linux-aarch64-${{ matrix.pyver }}
