upgrade netlify's ubuntu build image and node version before netlify deprecates jan 2026

[100ideas]

Natlify uses a containerized ubuntu environment to build diybiosphere whenever new commits are made to the repo (on 'master' I think).

"Support for the Focal build image will end on January 1, 2026. We recommend switching to the Ubuntu Noble 24.04 build image as soon as possible."

and

*"Node.js version 10.x has reached end-of-life. We recommend using Node.js 22.x, the current LTS version, instead."
