JsonNode.GetValueKind does not work on .NET 6 and 7, but page says it does.

[vebcaster]

This page https://learn.microsoft.com/en-us/dotnet/api/system.text.json.nodes.jsonnode.getvaluekind?view=net-8.0 says that JsonNode.GetValueKind applies to .NET 6, 7, 8, 9. But it does not work on 6 & 7. Only on 8 (and probably 9).

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

@vebcaster - When you say it doesn't work, what do you mean exactly? That the API isn't available?

On .NET 7 and earlier, you must reference the System.Text.Json NuGet package.

The page does show which package is needed for .NET 7:

I realize that the docs also show a package for .NET 8/9, because that version of the API essentially hides the "in-box" version. We're working on a fix for that, and I've added a link to this issue in that internal work item.
