Added Wretched Defiler spectre

[Lichmonarch]

Fixes #7684 .

Description of the problem being solved:

Wretched Defiler specter is missing

Steps taken to verify a working solution:

-Checked if specters are correctly shown in PoB and are available to be selected -Data taken from https://poedb.tw/us/Wretched_Defiler -I am unsure if the values for Revenant Boss Spell Projectile are accurate, seems quite low

This is not how we add Spectres to PoB. The files will be overwritten the next time out export scripts are run Have a look here https://github.com/PathOfBuildingCommunity/PathOfBuilding/pull/6014 so see how it is meant to be done
