Add OneSignal-Subscription-Id to all Update User requests

[nan-li]

Description

One Line Summary

Add the OneSignal-Subscription-Id header to all Update User requests, not just the ones with deltas.

Details

Motivation

• Previously, we added the OneSignal-Subscription-Id header to update user requests that had deltas in the body.
• Now, we will add this header to all update user requests. This endpoint may have expected this all along, but this was a recent ask of the SDK.

Scope

A header in Update User requests for backend to process.

Testing

Unit testing

None

Manual testing

Building and running on iPhone 13 with iOS 17.1.2.

1. Change SDK version and Sent a bunch of tags
2. Check honeycomb to see a bunch of requests with the header and that SDK version
