ci(docker_image): separate build steps for main image and cgct

[thunder-coding]

Also archlinux.org should be available now. So CI should pass now

Seems like archlinux.org hasn't fully recovered yet. will merge this as soon as CI goes green

@Maxython any reason why you are downloading gcc-libs from Arch Linux's repos instead of Ubuntu's. I don't see archlinux.org getting up anytime very soon. The DDoS attacks seems to be getting worse. And the site is now fully down as well instead of being partially down

My understanding is that:

1. an Arch Linux container is used to compile the modified GNU/Linux cross-compiler that will be used to compile the glibc-packages
2. the modified GNU/Linux cross-compiler is transferred to an Ubuntu container where it will be used to cross-compile the glibc-packages
3. the modified GNU/Linux cross-compiler was compiled on Arch Linux, but it will run on Ubuntu, so it needs the gcc-libs package from Arch Linux installed into its Ubuntu container in order to run because the gcc-libs package of Ubuntu is too old and doesn't work for that
4. In order to change this to make glibc-packages cross-compile entirely in one distro (entirely in Arch Linux or entirely in Ubuntu), significant rearchitecting of glibc-packages would be required that is not planned

Seeing this problem, I have an idea which is, could the download URL for the gcc-libs package be switched to this archive URL for Arch Linux gcc-libs version 15.1.1, which seems to be available and which will remain available for at least some time before being deleted, because it is an archive?

https://archive.archlinux.org/packages/g/gcc-libs/gcc-libs-15.1.1%2Br7%2Bgf36ec88aa85a-1-x86_64.pkg.tar.zst

Failed to fetch http://security.ubuntu.com/ubuntu/dists/noble-security/main/dep11/Components-amd64.yml.gz File has unexpected size (25213 != 25318). Mirror sync in progress?

seems like a temporary failure
