    Use the eslint plugin for TypeScript
    
    Since the deprecation of tslint, eslint can parse and provide
    diagnostics for TypeScript code too, if configured appropriately.
    Hence, we don't need to do anything special to get TypeScript
    support in Builder, other than to enable the plugin.
