update actions to use node js 24

[marionbarker]

Purpose

Update GitHub actions to use Node.js 24 before the required date of June 2, 2026.

See: https://github.blog/changelog/2025-09-19-deprecation-of-node-20-on-github-actions-runners/

Thanks to Odd Stoltenberg for the alert.

Method

Step 1: Update all the yml files to use actions/@checkout5.
Step 2: (See next comment), update the build file to use actions/upload-artifact@v6

Test

Push this branch (update/node-js-24) to GitHub user docs-test LoopFollow fork.

• set branch to default
• run nominal actions
  • ✅ https://github.com/docs-test/LoopFollow/actions/runs/23008627196
  • ✅ https://github.com/docs-test/LoopFollow/actions/runs/23008861450
  • ✅ https://github.com/docs-test/LoopFollow/actions/runs/23008910368
  • ✅ https://github.com/docs-test/LoopFollow/actions/runs/23010826612

However, build still has warnings for two jobs. I opened issues for those two repositories.

The final action will automatically be run when this PR is merged to dev.

Status

Open this but convert to a draft for now. Once all node 20 actions are updated to 24, then this will be considered for inclusion.

Next Step

The upload-artifacts has a v6 which uses Node js 24.
After adding that change, the number of warning messages is down to only one from the `Fork-Sync-With-Upstream-action.

Test

The final repo, aormsby/Fork-Sync-With-Upstream-action, was updated to use node 24 instead of 20 and tagged as v3.4.2.

Tested using docs-test Github username.

Successful build with no warning messages:

This will be a squash and merge.
