ci: install modern versions of chrome and node (#453)

The [build is failing trying to install chrome
126](https://app.circleci.com/pipelines/github/dequelabs/axe-core-gems/839/workflows/7a2c5f9d-709b-42de-83dc-9a803c8671ff/jobs/1834).
Unpinning the chrome version so it will install latest. Also updated the
node version while I was there.

No QA required
