fix(libs): restore ElvUI-namespaced Ace3 stack clobbered by sweep

The coa-ace3 sweep (commits 0c130e0..5ea6e44, before coa-elvui was added to
EXCLUDED_FORKS in coa-ace3 tools/sweep.py) overwrote ElvUI's customized,
-ElvUI-namespaced Ace3 libs with plain canonical ones. ElvUI registers libs
as AceLocale-3.0-ElvUI and the AceConfig-3.0-ElvUI family (plus -ElvUI
widgets that don't exist in canonical), so the clobber left them
unregistered: ElvUI failed to init (16 locale 'L' errors) and /ec would not
open. Restores ElvUI/Libraries/Ace3/AceLocale-3.0 and the
ElvUI_OptionsUI/Libraries/Ace3 stack to their pre-sweep state (5021fd1).
coa-elvui is now in EXCLUDED_FORKS, so this won't be re-clobbered.
