Update SubCategories_Electrical.cfg (KSP-IE quick fix)

[Gordon-Dry]

see https://forum.kerbalspaceprogram.com/index.php?/topic/168456-18x-filter-extensions-no-localization/&do=findComment&comment=3706171

The problem is that KSP-IE adds a block

    RESOURCE
    {
        name = ElectricCharge
        amount = 0
        maxAmount = 0.001
        isTweakable = false
        hideFlow = false
    }

to every part with ModuleDeployableSolarPanel.

So does FilterExtensions show all solar panels in the subcategory for "Power Storage".

This change fixes that, although not as I wanted (see forum post).
