Some more python.org updates:
We show a chart of supported Python versions at https://devguide.python.org/versions/ but that site is for developing CPython. So now it's also at https://www.python.org/downloads/
The "superseded by" had better styling, and added an EOL warning for older ones.

When creating a new release in the admin interface, prefill the release notes link to something like https://docs.python.org/3.15/whatsnew/3.15.html for pre-releases and https://docs.python.org/release/3.14.4/whatsnew/changelog.html for full releases.
