[PATCH 3/3] ci: pin linux32 to ubuntu-24.04 to restore networking

From: Harald Nordgren via GitGitGadget <gitgitgadget@gmail.com>

Message-ID: <37e837ef88b91d3c745fb05466bf30ec1afae680.1793530936.git.gitgitgadget@gmail.com>
In-Reply-To: <pull.2478.git.git.1793530936.gitgitgadget@gmail.com>

From: Harald Nordgren <haraldnordgren@gmail.com>

The linux32 job fails DNS resolution before checkout because Docker 29.4.2's seccomp profile on Ubuntu 26.04 blocks socketcall in i386 glibc containers. Ubuntu 24.04 avoids this host-side regression.
