Feat: Better feedback on timeout due to aria-busy

[DavidAtImpactCubed]

As a developer or tester using argos ci in cypress, I would like to see better feedback when argosScreenshot times out due to aria-busy tags being present, so that I can quickly identify what is causing the timeout and fix it.

Description

I'm new to argos (and cypress), and I just spent a fair amount of time trying to work out why my argosScreenshot was timing out, but when using the built-in cy.screenshot it didn't. By looking through the code on GitHub and reading the docs, I eventually realised that I had an element with an aria-busy that became hidden but remained in the dom.

An error message telling me why the timeout occurred would have saved me a lot of time!

Thank you for the great tool.
