patch(cli-utils): Add VSCode detection and warnings

Resolves #194

Summary

This PR adds an addition to the doctor command that attempts to detect VSCode extensions.

When VSCode is installed and the GraphQL Syntax extension for it isn't installed, a warning is issued with a link to the extension.

When the suggested extensions file or the installed extensions contain the VSCode GraphQL Language Service extension and a GraphQL Config is present a warning is issued to prompt the user to check whether documents is targeting their files correctly.

This doesn't actually use graphql-config to validate the config, since that's quite a huge package for what it does (large dependency to handle TS & ESM files). So, unless we really need that, or want to just load the module from the user node_modules, I'd say this should be good enough.
