[lucas-zimerman]

DESCRIBE YOUR PR

Tell us what you're changing and why. If your PR resolves an issue, please link it so it closes automatically.

Fix Value cannot be null. (Parameter 'bytes') when users copy/paste this code into their servers.

This happens because on the same doc, those values can be null

properties.Headers.Add("sentry-trace", SentrySdk.GetTraceHeader()?.ToString());
properties.Headers.Add("baggage", SentrySdk.GetBaggage()?.ToString());

So we add some null checks before retrieving the trace or baggage and everyone gets happy!.
