Published kiota packages depend on DiagnosticSource < 8.0.0

[charlesroddie]

kiota packages such as Microsoft.Kiota.Abstractions 1.7.1 (published today) require System.Diagnostics.DiagnosticSource (>= 6.0.0 && < 8.0.0).

The explicit failure to work with 8.0.0 creates a lot of problems for packages released together with dotnet 8 which bring in DiagnosticSource 8.0.0. For example we get build failures with Microsoft.Extensions.Http 8.0.0 -> Microsoft.Extensions.Diagnostics 8.0.0 -> Microsoft.Extensions.Diagnostics.Abstractions 8.0.0 -> System.Diagnostics.DiagnosticSource (>= 8.0.0) .

Thank you for using kiota and for reaching out.
I just put together #150 to start the process here.
We'll need to cascade the changes. For this to be entirely available, see microsoft/kiota-serialization-json-dotnet#105
