Migrates to .slnx solution file format

Updates the project to use the new .slnx solution file format, replacing the old .sln format.

This change improves solution loading times and provides a cleaner, more structured approach to managing project dependencies, especially as the project grows.

The .gitignore and .gitattributes files are updated to reflect the new file extension.
The build workflows are also updated to use the new solution file.
