revert: drop Genshin's Miliastra Pass source

Fandom's Event page, an existing source, already lists the pass as
"Silvery Moonlight Chronicle" with the same dates, and the merge folded
the new copy into it. The feed was unchanged, so a second source for one
event is cost with nothing to show. This reverts 9f8150f.
