wheel CI: Always use latest minor version of cibuildwheel
By removing the exact minor and patch version of the cibuildwheel action, it will always use the latest minor/patch version.

This ensures the latest Python versions are always used to build wheels.

Major version updates will be handled by #49475 for GitHub Actions.
My mistake, cibuildwheel (currently) doesn't allow this and requires pinned `major.minor.patch` versions specified. So closing this PR.
