Update default CNB builder image to `heroku/builder:24`

[edmorley]

We (Heroku) released heroku/builder:24, our new CNB builder image version based upon Ubuntu 24.04 LTS, in June: https://github.com/heroku/buildpacks/discussions/12 https://github.com/heroku/cnb-builder-images#available-images

Currently this project's default CNB builder image is heroku/builder:22: https://github.com/Qovery/engine/blob/f11361bd076fa07ded51ec1ff535ba6946ed3451/src/build_platform/local_docker.rs#L31-L32

It would be great to update the default CNB builder image to heroku/builder:24.

The heroku/builder:24 builder is now a multi-architecture image (AMD64 + ARM64), and offers smaller run image sizes thanks to dropping unnecessary build-time dependencies from the run image. The list of included buildpacks (and their versions) is identical between heroku/builder:22 and heroku/builder:24.

For more information on the differences between the two images, see: https://devcenter.heroku.com/articles/heroku-24-stack#what-s-new https://devcenter.heroku.com/articles/heroku-24-stack#upgrade-notes https://devcenter.heroku.com/articles/stack-packages
