Refactor CI setup for Python 3.10

Upgraded the GitHub Actions workflow to explicitly set up Python 3.10.
Simplified the installation process by using pip to upgrade and install
necessary Python packages such as h5py, setuptools, wheel, and build,
rather than installing individual Python and pip packages via apt-get.
This ensures a more standardized and up-to-date environment for CI
processes. Removed explicit python3 references in favor of the
actions/setup-python environment, aligning with the GitHub Actions best
practices.
