Send user.ip_address = {{ auto }} when sendDefaultPii is true

[bruno-garcia]

If no explicit IpAddress was set by the user code (or framework integration) the SDK should set {{ auto }} which tells the server to infer the IP Address to client connection as the user.ip_address.

This is true for all SDKs. Like: getsentry/sentry-dotnet#561

I believe it should set "{{auto}}" ? @bruno-garcia

Yep @lucas-zimerman is right, thanks for pointing this out
