Deduct gas fee from zkauth address

[Mdaiki0730]

Description

Deduct the gas fee that would have been deducted by DeductFeeDecorator from zkauth address
Mostly the same as DeductFeeDecorator.AnteHandle.

finschia-sdk/x/auth/ante/fee.go

Line 75 in df06ee1

func (dfd DeductFeeDecorator) AnteHandle(ctx sdk.Context, tx sdk.Tx, simulate bool, next sdk.AnteHandler) (newCtx sdk.Context, err error) {

In the future there should be a way to branch out with zkauth more generally.
