Move cibuildwheel config to pyproject.toml; other consistency fixes (#…

…1717)

This PR has a few leftover consistency fixes for the various GitHub Actions workflows, bringing the Traits workflows in line with others in ETS

- Move config for `cibuildwheel` into `pyproject.toml`
- Use Python 3.10 instead of Python 3.8 for single-version workflows (style checks, doc build)
- Update and uniformise action versions
- Remove unnecessary package installs and updates (especially `pip` updates: the `setup-python` action already updates pip to the latest  version)
