[v18.x] "Test and upload documentation to artifacts" workflow broken on v18.x-staging.

[richardlau]

The Test and upload documentation to artifacts workflow is now failing for v18.x-staging. It looks to be caused by calling actions/setup-node with lts/* which now picks up Node.js 22.

e.g.

• https://github.com/nodejs/node/actions/runs/11651030870/job/32440486759 ran with Node.js 20.18.0 and passed.
• https://github.com/nodejs/node/actions/runs/11682099987/job/32528534043 ran with Node.js 22.11.0 and failed.

Example failure:

=== release test-doctool-json ===
Path: doctool/test-doctool-json
Error: --- stderr ---
node:assert:137
  throw err;
  ^

AssertionError [ERR_ASSERTION]: Unexpected global(s) found: navigator

  code: 'ERR_ASSERTION',
  actual: undefined,

Workflow may also be broken for v20.x-staging: https://github.com/nodejs/node/actions/runs/11686859060/job/32543621127 (from a closed pull request -- we haven't pushed to v20.x-staging recently to trigger the workflow).

Opened #55755 to pin the workflow to Node.js 20 for v20.x-staging.

Fixed by #55755.
