[0.74] Fix OfficeReact.Win32 nuget layout

[vmoroz]

Description

Fix layout of the OfficeReact.Win32 nuget.

Type of Change

• Bug fix (non-breaking change which fixes an issue)

Why

Currently OfficeReact.Win32 nuget has the following issues:

• It has two jsi folders. One of them is missing the versioning.
• The node-api folder is missing node_api.h and and node_api_types.h files.

What

Updated the Layout-MSRN-Headers.ps1 script to address the issues:

• Copy the missing Node-APi files
• Copy the versioned JSI files to node_modules\react-native to ensure that both JSI folders are the same.

Testing

Ran the script locally to ensure the files copied correctly to the destination folders.

Changelog

Should this change be included in the release notes: yes

Fix layout of the OfficeReact.Win32 nuget. Add missing Node-API headers and use versioned JSI headers.
