  1. Update Metro to ^0.80.0 - don't pin to exact version (facebook#41219)

    Summary:
    
    Bump to the latest Metro release. This includes minor breaking changes to Metro subpackages that should *not* be visible to RN users.
    
    Metro release notes: https://github.com/facebook/metro/releases/tag/v0.80.0
    
    ## Moving to unpinned versioning
    Metro is a multi-package project, and not pinning to an exact version means multiple versions of `metro*` packages may appear in an RN project.
    
    This isn't unusual in the NPM ecosystem and *shouldn't* be a problem, but historically has caused issues (eg facebook#34714, facebook/metro#1017). The root cause of all of these issues, as far as we know, was fixed in facebook/metro@6d46078, a bug where Node hierarchical resolution was effectively sidestepped via a relative worker path, resulting in a mismatch between transformer and host process.
    
    In addition, the fact that `react-refresh`, `metro-react-native-babel-transformer` and `metro-react-native-babel-preset` are now fully moved into the `react-native/` scope and versioned with React Native means there are no circular dependencies between React Native and Metro, explicit or implicit, and we're much more clearly decoupled.
    
    So, we're moving to caret versioning to allow React Native users to pick up Metro fixes and features without requiring React Native releases and user upgrades.
