Docs: update screenshot

@aqualls: To end the discussion about this specific change in !71910 (merged), here an update to the newest UI.

@marcel.amirault: I took your screenshot from there, as you state it`s current. Just scaled it down to the width of the old one. So, credits to you - thanks for providing! And if my proceeding/practice here is an offense/bad habit just close this MR.

The general discussion on how to proceed in #214237 is untouched by this.
