Bundle extension in production build

➜  vscode-hadolint git:(master) ✗ npx vsce package                              
Executing prepublish script 'npm run vscode:prepublish'...

This extension consists of 451 files, out of which 230 are JavaScript files. For performance reasons, you should bundle your extension: https://aka.ms/vscode-bundle-extension . You should also exclude unnecessary files by adding them to your .vscodeignore: https://aka.ms/vscode-vscodeignore

Not sure if there is any actual performance gain, but this message is annoying as hell.

We need to use either webpack, parcel, or any JS bundler to bundle the extension.
