What article on docs.github.com is affected?

https://docs.github.com/en/actions/using-github-hosted-runners/using-github-hosted-runners/about-github-hosted-runners

What part(s) of the article would you like to see updated?

The documentation currently says that Ubuntu 20.04 is a supported image to use for GitHub-hosted GitHub Actions runners.

This issue says that Ubuntu 20.04 will be fully unsupported on 2025-04-15 and that date has now been passed and this pull request was made to remove Ubuntu 20.04 references from the actions/runner-images repository and has now been merged. As a result, Ubuntu 20.04 should be removed from the supported GitHub-hosted runners list.
