Explicity set user.ip_address: {{auto}}

[cleptric]

Description

For client side SDKs, we need to explicitly set the user's IP address to {{auto}}, if the property was not set by the user.

By default, SDKs should not set {{auto}} and only do so if sendDefaultPii was set to true by the user.

Docs: https://develop.sentry.dev/sdk/expected-features/data-handling/

See getsentry/relay#4431

@bitsandfoxes I'm pretty sure Unity does the right thing (the dotnet sdk that is, which would be true then for Unity, Xamarin and PowerShell. But could you please double check?

sentry-cocoa already sets {{auto}} in https://github.com/getsentry/sentry-cocoa/blob/72e34fae44b817d8c12490bbc5c1ce7540f86762/Sources/Sentry/SentryClient.m#L781-L786, marking as done

for spans, relay populates the client.address attribute (even if no explicit auto is set):

for sessions there's the ip_address attribute:
