Update XML configurations based on Microsoft best practices
- Remove Language ID from uninstall XMLs to uninstall all languages
- Change language settings from "MatchOS" to "MatchInstalled" in install XMLs
- Remove update channel specifications from Visio and Project XMLs to match existing Office installations
- Add reference links to Microsoft documentation for supported product IDs
- Update comments to better explain language selection behavior
These changes improve multi-language support and prevent channel conflicts when installing Visio/Project alongside existing Office installations.
