[0.76] `NU1004: The package references have changed for native` with New Arch enabled

[tido64]

Problem Description

Building RNW with New Architecture enabled, I get this error:

× Build failed with message 1>D:\react-native-test-app\node_modules\react-native-windows\Microsoft.ReactNative\Microsoft.ReactNative.vcxproj : error NU1004: The package references have changed for native. Lock file's package references: boost:[1.83.0, ), Microsoft.JavaScript.Hermes:[0.1.23, ), Microsoft.SourceLink.GitHub:[1.1.1, ), Microsoft.Windows.CppWinRT:[2.0.230706.1, ), Microsoft.WindowsAppSDK:[1.5.240227000, ), project's package references: boost:[1.83.0, ), Microsoft.JavaScript.Hermes:[0.1.23, ), Microsoft.Windows.CppWinRT:[2.0.230706.1, ), Microsoft.WindowsAppSDK:[1.5.240227000, ).The packages lock file is inconsistent with the project dependencies so restore can't be run in locked mode. Disable the RestoreLockedMode MSBuild property or pass an explicit --force-evaluate option to run restore to update the lock file. [D:\react-native-test-app\example\windows\Example.sln]. Check your build configuration.

Where Microsoft.SourceLink.GitHub is no longer present. Removing node_modules/react-native-windows/Microsoft.ReactNative/packages.fabric.lock.json gets me further.

Looking in the npm package, I see packages.fabric.lock.json and packages.lock.json are present. Should they be included in the package?

Two issues:

1. Yes, the lock files shouldn't be present in the npm package.
2. Building new arch against source out of this repo is not officially supported, please use the nugets as per the cpp-app template
