Why is this needed? It seems like it might be the cause of the CI failures: C:/a/vscode-cpptools/vscode-cpptools/Extension/node_modules/@types/vscode/index.d.ts(4497,3): error TS2374: Duplicate index signature for type 'string'.
Our current VS Code dependency is 1.67.0, so including a type dependency on VS Code version 1.99.1 seems incorrect.
