Update version and improve build process for packaging

Updated project version to 1.2.0.3 in `EnvelopeGenerator.DependencyInjection.csproj`.
Replaced line endings in `_DepDlls` for consistency. Added a new
`RebuildDependenciesBeforePack` target to ensure all dependencies
are rebuilt for `net7.0`, `net8.0`, and `net9.0` before packaging.
Improved formatting in `BundleReferencedDlls` for better readability.
