License for this repository

Considering this repository is nearly all documentation nowadays, we should probably integrate the updated license for Python documentation from the CPython repository:

As this is a license change, this is something the PSF must do. How do we best proceed here?

Start by comparing the repository's LICENSE with the updated LICENSE in the CPython repository, focusing on the proposed Python documentation and Zero-Clause BSD terms. Confirm the PSF's required process before editing; done means the authorized license text is integrated and the repository's documentation licensing is correctly represented.
