Describe your bug

I am running Ubuntu 20.04 and using this in my apt sources:

deb https://deb.nodesource.com/node_18.x focal main
deb-src https://deb.nodesource.com/node_18.x focal main

The latest version of NodeJS 18.x I seem to be able to get on focal is 18.17.1 but it seems there are much newer versions of 18.x available - https://nodejs.org/en/about/previous-releases (e.g 18.20.5).

I'm wondering why Focal doesn't have the latest 18.x version? Thanks
