Fix/container test

[mjun0812]

This pull request improves Fedora and AlmaLinux support for CUDA setup in GitHub Actions workflows and documentation. The main changes include updating the container test matrix, expanding the README to clarify supported platforms, and providing a new example for installing CUDA on Fedora-based distributions.

Platform and container support:

• Updated .github/workflows/container-test.yml to remove the deprecated manylinux2014_x86_64 container and add manylinux_2_28_x86_64, ensuring compatibility with newer manylinux standards.

Documentation improvements:

• Added Fedora and AlmaLinux to the list of supported platforms and containers in the README, clarifying that both Debian-based and Fedora-based distributions are now supported.
• Expanded the list of tested Linux platforms in the README to include Fedora, AlmaLinux, and manylinux_2_28_x86_64, reflecting the broader compatibility.

Usage example:

• Added a new example to the README showing how to install CUDA on Fedora-based distributions, including logic for installing system dependencies with dnf, yum, or apt-get.
