Issue Type: Feature Request

I'm using a node.js library (puppeteer; installed with npm) which for each <blah>.d.ts file has <blah>.d.ts.map and <blah>.js files. In my code, rightclicking on any function/class/member defined in the .d.ts files and choosing "Go to implementations" (or just Ctrl+Leftclicking it) takes me to .d.ts file instead of .js file. Also, the .d.ts file VSC takes you to comes from %localappdata%\Microsoft\TypeScript\4.0\node_modules\@types\puppeteer dir instead of <projectroot>\node_modules\puppeteer\lib\cjs\puppeteer\common where the source code lives. It's mildly infuriating to have to search through library's source files and find the one .js file.
Example:

const puppeteer = require("puppeteer");
(async () => await puppeteer.launch(...))();

Right-click the launch function, "Go to implementations" and VSCode will happily show you the .d.ts file.
