[eventstream-marshaller]: Int64 does not throw error for 2^63

[trivikr]

Describe the bug

Int64 does not throw error for when number is slightly larger than 2^63-1

We use the test code with value for 2^63

Expected Behavior

Throws error with following template:

${number} is too large (or, if negative, too small) to represent as an Int64

Current Behavior

Does not throw error

Reproduction Steps

import { Int64 } from "@aws-sdk/eventstream-marshaller";

// Below code doesn't throw error.
Int64.fromNumber(9_223_372_036_854_775_807);
