fix: Add Armour Cruncher to the list of spectres.

Fixes #5127 .

Description of the problem being solved:

Armour Cruncher was missing from the Spectre list.

Steps taken to verify a working solution:

• Checked that Armour Cruncher wasn't in the original list
• Added an entry for Armour Cruncher into the Spectre list
• Checked that the values are correct and values are calculated when adding Armour Cruncher to the list of spectres in the build

Before screenshot:

Armour Cruncher missing from list.

After screenshot:

Raise Spectre added to the Build.

Armour Cruncher now displays on the list and values are calculated.

When spectre is added the build calculations update accordingly.

This is not how we add additional spectres to PoB. We do not manually change the .lua files as they are auto-generated when we run export scripts on the game files. In order to add new spectres to PoB you need to edit the relevant .txt file then run the export scripts.
Have a look here at how the Pale Angel spectre was added https://github.com/PathOfBuildingCommunity/PathOfBuilding/pull/3639/files
