feat(hyprdrive): default wallpaper -> ESA/Hubble "Rings of Relativity"

Swap the module's default background.jpg for ESA/Hubble Picture of the Week
potw2050a, "Rings of Relativity" (GAL-CLUS-022058s, one of the most complete
Einstein rings observed). Update CREDITS.md and the hyprdrive.sh install-module
comments to match. Credit: ESA/Hubble & NASA, S. Jha; Ack. L. Shatz — CC BY 4.0.
