test(golden): accept the 2 reviewed static-background moon frames (#718)

The golden-images artifact of Validate run 36790529482 (16616f09, Linux,
Chromium 151.0.7922.34) reports exactly the two new #718 scenes as
missing-baseline and every other scene as passed:

- static-bg-moon-gibbous-white-light: a waxing gibbous moon on the plain
  white static background, top-left behind the plan.
- static-bg-moon-crescent-south-dark: the southern-hemisphere crescent on
  the dark static background, top-left behind the plan.

Both frames were reviewed: the moon sits behind the plan in the top-left
corner on either background, as the spec asks. The other 190 baselines are
kept byte-for-byte; 145 environment witnesses matched.

Issue: #718
User-Visible: no
Release: v1.79.0-beta.2
