ci: bump Linux runners and Docker base image to ubuntu 24.04#7905
Merged
Conversation
dfx 0.32.0 is built against glibc 2.38/2.39, but ubuntu-22.04 only ships glibc 2.35, so linux jobs fail with `version GLIBC_2.39 not found`. Mirrors dfinity/snsdemo#595.
The reproducible-build image installs dfx 0.32.0, which needs glibc 2.38/2.39; ubuntu:22.04 only ships glibc 2.35. node is still pinned via `n` from .volta.node, so the build toolchain is unchanged otherwise.

ubuntu-24.04 renders fonts slightly differently than 22.04, so the neuron-details and neurons-table baselines needed updating.

Motivation
The upcoming
dfx 0.32.0(used by the nextsnsdemorelease — dfinity/snsdemo#594) is built against glibc 2.38/2.39, butubuntu-22.04only ships glibc 2.35, so any job that installs dfx 0.32.0 fails withversion 'GLIBC_2.39' not found.This PR moves the Linux toolchain to
ubuntu-24.04(glibc 2.39) as a prerequisite, so the dfx bump (#7903) can land cleanly. snsdemo did the same in dfinity/snsdemo#595.This change is safe to merge on its own with the current
dfx 0.31.0.Changes
