r.lsp.snippet_support Setting is Missing

[kebb549575]

I have installed the languageserver package in my R installation. The languageserver README mentions the r.lsp.snippet_support setting to enable snippets in auto completion. However, when I look at my REditorSupport settings the only lsp settings available are:

• Lsp: Args
• Lsp: Debug
• Lsp: Diagnostics
• Lsp: Enabled
• Lsp: Lang
• Lsp: Multi Server
• Lsp: Prompt To Install
• Lsp: Use_stdio

I've manually added "r.lsp.snippet_support": true to my user settings in VS Code in Linux but it's immediately grayed out when I Ctrl+S. That tells me this r.lsp.snippet_support setting doesn't exist anymore. Where is it?
