This update enhances our testing process by allowing developers to easily specify the Chrome/Chromium browser version used during tests. This simplifies debugging issues related to browser-specific problems and ensures consistent testing across different browser versions. It's a small change that improves our ability to quickly identify and resolve browser-related bugs.

This is mainly used to more easily provide an arbitrary version of Chrome/Chromium to debug browser's version specific breaking changes.
