Compiling doc outdated for Ubuntu ≥24.04 (dependencies)

[lapineige]

Is there an existing issue for this?

• I checked and did not find my issue in the already reported ones

Describe the bug

Currently the documentation on how to compile is outdated for Ubuntu 24.04 and newer.

This part in particular https://github.com/darktable-org/darktable?tab=readme-ov-file#ubuntu, regarding the dependencies.
sed -e '/^#\sdeb-src /s/^# *//;t;d' "/etc/apt/sources.list" will give an invalid result, with an empty file.
Here is the explanation and workaround : https://askubuntu.com/questions/1512042/ubuntu-24-04-getting-error-you-must-put-some-deb-src-uris-in-your-sources-list/1512043#1512043

I can't adapt the command myself, but at least /etc/apt/sources.list should be replaced by /etc/apt/sources.list.d/ubuntu.sources and the sed syntax adapted, I believe.

As a temporary workaround, one could edit this /etc/apt/sources.list.d/ubuntu.sources file, add deb-src after deb, do sudo apt-get update and then sudo apt-get build-dep darktable, then revert the edit.

Steps to reproduce

Just copy paste the commands.
