Why doesn't the netstandard2.0 build work for net472? Is this because of the ValueTuple problem?

I dont know if it's that, but I am getting:

Project '[x].csproj' targets 'net8.0-windows'. It cannot be referenced by a project that targets '.NETFramework,Version=v4.7.2'.

But [x].csproj has <NetFxVersionMoniker>net472</NetFxVersionMoniker>.

This is interesting because the core Arrow assembly targets netstandard2.0 and not net472 and I guess that one doesn't cause a problem in this scenario?

Let's be consistent between projects and if we're adding net472 here then I think we should also add netstandard2.0 to Apache.Arrow.Adbc.Drivers.Apache.csproj. This will require a minor edit to lines 91-93 of SqlTypeNameParser.cs to call the HashSet<> ctor instead of using ToHashSet().
