Decimal IR for DivWithDefault has the wrong return type

[michelchan]

The SDK doesn't match the IR for Decimal.divideWithDefault. This is causing issues when implementing it properly in Morphir-Scala because it doesn't match.

DivWithDefault SDK implementation that returns Decimal:

morphir-elm/src/Morphir/SDK/Decimal.elm

Lines 238 to 242 in cdccf45

	{-| Divide two decimals providing a default for the cases the calculation fails, such as divide by zero or overflow/underflow.
	-}
	divWithDefault : Decimal -> Decimal -> Decimal -> Decimal
	divWithDefault default a b =
	div a b |> Maybe.withDefault default

DivWithDefault IR that returns Maybe Decimal:

morphir-elm/src/Morphir/IR/SDK/Decimal.elm

Line 49 in cdccf45

, vSpec "divWithDefault" [ ( "default", decimalType () ), ( "a", decimalType () ), ( "b", decimalType () ) ] (maybeType () (decimalType ()))

It should be Decimal.
