Update Ben Karpinski's photo attribution link from Fall 2019 wallpapers

[karenkliu]

Description:

Currently, Ben Karpinski's photo attribution link is set as www.benkarpinski.com/landscapes. He has requested that we update it to http://bklandscapes.com/. His image is included in the Fall 2019 batch of new wallpapers.

Test plan

1. Load picture (thumbnail shown above)
2. Make sure image is attributed properly to Ben Karpinski

Marking as QA/Blocked for now since brave/brave-core#4398 was reverted.

@LaurenWags it should be there actually- I did open a revert, but we fixed a different way 😄 Let me make a note there (my bad)

Comment left brave/brave-core#4398 (comment) 😄 Removing QA/Blocked label

Issue from description still reproduces. When Ben Karpinski's image is shown, his image is still attributed to https://benkarpinski.com/landscapes/ not http://bklandscapes.com/ as mentioned in the description.
