Considering the recemt API changes made in k6 browser for which the browser initialization/closing procedures are no longer delegated/exposed to the end user, but instead are automatically handled by k6 browser implementation from the Go layer, currently the browser.on() method is not providing any value as we are only supporting the disconnect event.

Therefor, a decision is made to not expose this method by now, until more events types are supported.
