Summary of Changes

Checkout Action:

Updated from actions/checkout@v2 to actions/checkout@v3.
Python Setup:

Added steps to set up Python only for x86_64 architecture using actions/setup-python@v4.
Added a step to build the source distribution (sdist) only for x86_64.
QEMU Setup:

No changes to the QEMU setup step.
Build Wheels:

Updated from pypa/[email protected] to pypa/[email protected].
Modified the CIBW_SKIP and CIBW_BUILD environment variables to skip cp36-* and cp37-* and to build all CPython versions (cp*).
Docker Smoke Tests:

Added Python 3.11 to the list of versions for smoke testing.
Upload Artifact:

Updated from actions/upload-artifact@v2 to actions/upload-artifact@v3.
Evaluation
Updates to Actions:

The updates to use the latest versions of actions (checkout, setup-python, upload-artifact) are appropriate and align with best practices to ensure compatibility and security.
Conditional Steps:

Adding conditional steps to set up Python and build the source distribution only for x86_64 architecture is efficient and reduces unnecessary steps for other architectures.
Build and Test Configurations:

Updating cibuildwheel version and modifying CIBW_SKIP and CIBW_BUILD variables to include all CPython versions and exclude older versions (cp36-, cp37-) is a good approach to maintain up-to-date builds and focus on supported versions.
Including Python 3.11 in smoke tests ensures broader compatibility testing.
Recommendations
Testing: Ensure that the workflow runs successfully with the new configurations and that all tests pass.
Documentation: Update any relevant documentation to reflect these changes, especially if there are new requirements or dependencies.
Further Review: If there are any additional changes or feedback from reviewers, address them accordingly.
The changes look well-structured and align with best practices. If verified and tested, you can proceed with merging these changes.
