Upgrade Sarif.Multitool to a supported .NET runtime

[paulomorgado]

When running Sarif.Multitool installed from https://www.nuget.org/packages/Sarif.Multitool/4.4.0, I get:

$ sarif                                                                                                                                                                                                                             You must install or update .NET to run this application.

Any progress? Just tried to run sarif.exe 4.3.3 on a build VM (Winserver 2022) with the current dotnet LTS (8.0) and got the following error:

S:\a\_tool\Sarif.Multitool\4.3.3\x64\sarif.exe convert 'S:\a\1\a\CodeAnalysisLogs\ConsoleApplication1.cppcheck.xml' --tool CppCheck --output 'S:\a\1\a\CodeAnalysisLogs\ConsoleApplication1.cppcheck.xml.sarif' --log ForceOverwrite
You must install or update .NET to run this application.

##[debug]task result: Failed

At this point, supporting dotnet 6 will buy you two weeks of running on a supported dotnet LTS. Any chance you could target 8.0?

Would you take a PR?

I mean, or just deprecate it 🤷‍♂️
