Update/fix settings in .vscode directory (#4722)

Two files have been modified, which was added to the repo 5 years ago
and never touched again:

The `.vscode/launch.json` file was outdated and didn't actually work, as
it expected `tdd` to exist in the path.

The `.vscode/settings.json` file was outdated and used a config property
no longer supported. The proper equivalent setting would have been:

    "debug.javascript.autoAttachFilter": "always"

But I don't think we want that as it will auto-attach a debugger to
every script you run in the console. I've opted for removing this
altogether.
