Netlify build image update

Hello, Netlify is requesting that this site update its build image:

> This project is using an older build image that will reach end of support in January 2026. Please update your build image [here](https://app.netlify.com/projects/blog-brigade-sh/configuration/deploys#build-image-selection).

> ⚠️ 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.

I can help with this if no maintainer has access to the Netlify project (though if that is the case, we need to correct that). But I prefer that the projects handle this update themselves, as there is a risk, however slight, that upgrading the build image could break the site build in a way I would be unable to correct if I make the update.

Open the linked Netlify project configuration and inspect the Deploys build image selection. Switch the site from the unsupported Focal image to Ubuntu Noble 24.04, then verify that the Hugo site still builds and deploys successfully.
