Migrate from Node.js 20 to Node.js 24

[marc-barry]

Summary

setup-docker-builder (v1.4.0) uses node20 in its action.yml. GitHub has announced that Node.js 20 actions are deprecated and will be forced to run on Node.js 24 starting June 2, 2026.

Current behavior

Every workflow run that uses this action produces a warning annotation:

Node.js 20 actions are deprecated. The following actions are running on Node.js 20 and may not work as expected: ef12d5b. Actions will be forced to run with Node.js 24 by default starting June 2nd, 2026.

Requested change

Update the runs.using field in action.yml from node20 to node24.

This is our last dependency giving this warning in CI. All others have either cut a release or have a fix on main

This would be solved by #84 I think 😉
