Use an absolute URL for the package-page language link

When this README is rendered outside GitHub—specifically on PyPI, since pyproject.toml declares README.md as project.readme—the relative README.zh.md href resolves beneath the PyPI project URL, where repository files are not served, so the new Chinese switcher leads to a 404. Point this link at the absolute GitHub URL so the switcher also works on the package's published description.
