Missing Instructions for iOS Source Map Upload in React Native Migration Guide (5.x to 6.x)

Description

Summary

The current migration guide for upgrading Sentry in React Native projects from version 5.x to 6.x lacks instructions for updating the iOS project configuration related to source map uploads. This omission results in an incomplete migration guide and may lead to broken Release builds for iOS.

Description

The migration guide does not mention the need to update the "Bundle React Native code and images" build phase in the iOS project file to configure automatic source map uploads. This step is critical and is documented in the Manual Configuration section of the Sentry documentation.
Without these changes: debug builds in the iOS simulator function correctly, masking the problem but release archives crash on startup because the JS bundle is not correctly generated.

Suggested Solution

Update the React Native migration guide for version 5.x to 6.x to include clear steps for modifying the "Bundle React Native code and images" build phase, ensuring the necessary changes are included during migration.
