Steps to Reproduce

1. Clone this repo https://github.com/serglom21/sentry-ios-bundle-execution
2. Run the app on a simulator
3. Check Sentry for ui.load spans

Expected Result

The SentryUIViewControllerSwizzling only swizzles the UIViewControllers being in-app by design, because otherwise the SDK would instrument plenty of UIViewControllers that are just noise for users.

https://github.com/getsentry/sentry-cocoa/blob/7d88965b68a8e0439450ba54ab41844a8ba5bc10/Sources/Sentry/SentryUIViewControllerSwizzling.m#L76-L90

You can change this via the inAppIncludes option https://docs.sentry.io/platforms/apple/guides/ios/configuration/options/#in-app-include

I just noticed that we don't mention this anywhere here https://docs.sentry.io/platforms/apple/guides/ios/tracing/instrumentation/automatic-instrumentation/#uiviewcontroller-tracing so we should update the docs.
