Fix DateOnly / TimeOnly parameters is TestCaseUsage

[Dreamescaper]

Fixes #820 .

I had to update test project to use net8.0 here (to be able to actually test DateOnly / TimeOnly parameters), hope it's ok.

Updated mapping per TypeConverter updates:
https://github.com/dotnet/runtime/blob/main/src/libraries/System.ComponentModel.TypeConverter/src/System/ComponentModel/ReflectTypeDescriptionProvider.cs#L154

Had to update it to string from Type, as netstandard2.0 does not have DateTime/DateOnly/etc types.

This package is not needed on netstandard2.0

Appveyor build failed, but I'm not really fure why:
The running command stopped because the preference variable "ErrorActionPreference" or common parameter is set to Stop: .NETCoreApp,Version=v8.0

My time is very limited today due to new year's eve, but perhaps this is related to the cake tool? At least the bump to version 5.0 fails with

The running command stopped because the preference variable "ErrorActionPreference" or common parameter is set to Stop: Package "cake.tool" failed to restore, due to Microsoft.DotNet.ToolPackage.ToolPackageException: The tool package could not be restored.

So perhaps bumping the cake tool will solve the problem (I've not checked if there are any breaking changes between 3.2.0 and 5.0.0. Perhaps bumping to version 4 will be enough?

@Dreamescaper Sorry about the WIP and moving the PR to draft and back again. I was hoping that this was enough to retrigger the builds. I've updated cake to version 4 on master and I hope this is enough to solve the problem with AppVeyor

@mikkelbu
It seems to work just fine after merge from master, thanks for the help!

[mikkelbu]

The changes look sound @Dreamescaper. I'm a bit unsure why we need the bump to .NET8 as DateOnly and TimeOnly were already part of .NET 6, but I think I might be missing something obvious :).

Not that I've against the bump - I just thought from #677 that it would require update of the Roslyn Analyzer as well as larger consequential changes.

I've approved it, but I would prefer if @manfred-brands can take a second look before we merge this as I think he has a better understanding of the bump than I have (also I would like to test the generated nuget package locally).

[Dreamescaper]

Ooops. My bad. I don't know why I decided that I need to update to NET8.
I suggest to extract the bump to a separate PR.
