ci: bump publish job to Node 24 to escape broken npm toolcache on Node 22.22.2

The GitHub-hosted Node 22.22.2 image in the runner toolcache ships an
npm install whose bundled `@npmcli/arborist` is missing `promise-retry`,
so even `npm --version` aborts with MODULE_NOT_FOUND and the manual
self-upgrade can't run (--force doesn't help — npm crashes before
arguments are parsed). Node 24 has a clean toolcache and already ships
npm 11.x, so the same upgrade step succeeds normally.
