Updated versioning details in the `.csproj` file:
- Incremented `Version` to 1.1.0.
- Updated `FileVersion`, `AssemblyVersion`, and `InformationalVersion` to reflect the new version.
This update likely includes new features or enhancements while maintaining backward compatibility.
Updated project and solution files to rename and restructure
`DocumentOperator` to `DocumentService`. Modified project
references in `DocumentService.API.csproj`, `DocumentService.Application.csproj`,
and `DocumentService.Infrastructure.csproj` to reflect the new
naming convention. Updated `DocumentService.sln` to remove
old project references, add new ones, and adjust configuration
and nested project mappings accordingly. This change aligns
the project structure with the new naming convention.
