From https://bugs.python.org/issue45729

This link is empty in 3.9, 3.10 and 3.11 docs:

    {% trans pathto_license=license_file %}See <a href="{{ license_file }}">History and License</a>
    for more information.{% endtrans %}

I do not understand how these pathto_* things work and where they come from. The assignemnt looks backwards to me but it is working for other links in the same footer so it’s a bit baffling.
