test: add chrome for testing example

[MikeMcC399]

Situation

Cypress introduced support for Google Chrome for Testing in cypress@13.17.0.

Google restricted the use of the --load-extension flag in Chrome version 137 (May 2025) and above and continues to allow its use in Chrome for Testing. See also cypress@14.4.0 changelog.

This repo does not currently describe using Chrome for Testing.

GitHub runner images such as ubuntu-24.04 do not include Chrome for Testing. https://github.com/browser-actions/setup-chrome does however provides a JavaScript action to install Chrome for Testing in GitHub runners.

Change

• Add a workflow .github/workflows/example-chrome.yml

• Add a README section "Chrome for Testing"
