Fix cibuildwheel build configuration for manylinux_2_28 compatibility

- Add --plat manylinux_2_28_x86_64 flag to auditwheel repair command
- Add CONDA_PREFIX environment variable for pixi build environment
- Rename wheel-related pixi tasks to consistent wheel_* naming convention
  - build_wheels -> wheel_build_cibw
  - build_pypi_wheel -> wheel_build
  - build_pypi_repair -> wheel_repair
  - check_pypi -> wheel_check
  - test_pypi_wheel -> wheel_test
  - publish_pypi -> wheel_publish
  - publish_pypi_test -> wheel_publish_testpypi

This addresses GitHub issue #847 for manylinux_2_28 wheel compatibility
to support older Ubuntu (20.04) and Google Colab environments.
