Support multi-targeting and add NuGet metadata

Updated `EnvelopeGenerator.DependencyInjection.csproj` to support multiple target frameworks (`net7.0`, `net8.0`, `net9.0`) for broader compatibility. Added NuGet package metadata to enable publishing, including details like `PackageId`, `Authors`, and `RepositoryUrl`.

Upgraded `Microsoft.Extensions.Configuration.Abstractions` and `Microsoft.Extensions.DependencyInjection.Abstractions` to version `9.0.6`. Added a project reference to `EnvelopeGenerator.Domain`.

Modified `EnvelopeGenerator.sln` to adjust the build configuration for the project with GUID `{90FE0312-8C38-4347-9EA2-0A719E255D5C}`, setting `Debug` to use the `Release` configuration.
