feat: Support for Boolean and Number type as value in TracingUtils putAnnotation

[dmahapatro]

Is your feature request related to a problem? Please describe.
I came across a minor feature missing in TracingUtils. XRay SDK supports recording annotations as:

• Keys – Up to 500 alphanumeric characters. No spaces or symbols except underscores.
• Values – Up to 1,000 Unicode characters.

With key being a string and value can be a Boolean, Number, or String value.

However, TracingUtils just supports value as String, there is no support for Number, Boolean.

Describe the solution you'd like
Adding support for Number & Boolean like:

public static void putAnnotation(String key, Number value) {
  AWSXRay.getCurrentSubsegmentOptional()
    .ifPresent(segment -> segment.putAnnotation(key, value));
}

Describe alternatives you've considered
This is not a blocker because I can use String.valueOf(myIntValue)
