fix: OData v4 default de-serializer number conversion

[ZhongpinWang]

Closes #6042.

Replace the mistakenly used value.toNumber() with Number(value) in OData V4 default de-serializers.

Replace the mistakenly used value.toNumber()

I don't think this was a mistake. The expected input type for Edm.Decimal in Odata v4 is BigNumber, which has a .toNumber() function. But since both lead to precision loss, I wonder if either is even a good idea (BigNumber has functions to check if it's outside/within range).

Make sense. I didn't consider this. Then the question is why user received a string in the Decimal field right?
