See dotnet/roslyn#78208

I can see the CI failure is related to my change, but, I don't know how to track it down or resolve it.

Perhaps the server needs to be updated first? I just have no clue how to track down the process which is verifying the set of options here. @jasonmalinowski

@RikkiGibson you need to update the localization file to include the new string - https://github.com/dotnet/vscode-csharp/blob/main/package.nls.json

[dibarbet]

However - you also need to do some server side changes if you want to read it on the server. For example take a look at dotnet/roslyn#75224 and #7381

The client side needs to be combined with a server side PR exposing the option via LSP.

[RikkiGibson]

Thanks for the guidance @dibarbet. I believe I have the prerequisite changes ready to go on the LSP side in my PR dotnet/roslyn#78208.
