chore: Update saucelabs screenshot

[bsmth]

Description

I'm updating the screenshot & docs for Sauce Labs so it has up-to-date info.

Motivation

The screenshot shows an older UI.

Additional details

Ideally, we don't have screenshots of external products at all due to how quickly they go stale, but I went through the registration steps here so this older issue is fixed as it's probably worth refreshing.

Issues and PRs

Fixes #28034
