Fix Coiling Whisper applying to all Curses instead of just Hexes

[pjo256]

Fixes #8748 .

Description of the problem being solved:

Coiling Whisper reads "Targets are Unaffected by your Hexes" - 57a268c applied a -100% curse effect modifier to both hexes and marks, instead of hexes only.

Steps taken to verify a working solution:

• Enabled a mark (Assassin's Mark) on a skill gem. Equipping Coiling Whisper on dev disables the mark effect (6% crit chance)
• Re-enabled Assassin's Mark after this change, and confirmed the mark effect working (7.5% crit chance)

One small thing, when updating ModParser.lua, it's good to include the rebuilt ModCache.lua. The maintainers rebuild the cache themselves usually, but sometimes it gets missed.

Thanks, missed that after refreshing PoB locally
