Add vscode settings checks to doctor

[EddieIsNotAvailable]

Resolves #459 and adds missing checks for whether the recommended workspace VSCode settings are missing.

Summary

Adds new VSCode checks to the doctor command, to warn the user if they are missing any of the recommended VSCode settings, or if they have a known incompatible setting enabled:

Set of changes

Affects the cli package, particularly the doctor command.

Adds check to the workspace VSCode settings for whether any of the recommended settings are missing. These being:
{
"typescript.tsdk": "node_modules/typescript/lib",
"typescript.enablePromptUseWorkspaceTsdk": true
}

Adds check to the workspace and global VSCode settings for a setting incompatible with the recommended extension:
"editor.experimental.preferTreeSitter.typescript" : true

I don't believe there are any breaking changes.
