Configures NuGet package creation and artifact handling

Improves NuGet package creation and artifact management by:

- Adding 'artifacts' and 'nuget' folders to the build workflow's artifact paths to ensure proper packaging.
- Appending a trailing slash to the local NuGet package source path in the integration tests to align with expected path format.
- Modifying the integration tests project file to streamline package management and remove unnecessary project references, instead relying on published NuGet packages.
- Adjusts the location of the Sigurn.Serialize.Generator.dll in the Sigurn.Serialize project to correctly package it as an analyzer.
