Tabledrag library depends on non-existent libraries

Problem/Motivation

The drupal.tabledrag.ajax library entry is currently:

drupal.tabledrag.ajax:
  version: VERSION
  js:
    misc/tabledrag-ajax.js: { }
  dependencies:
    - core/ajax
    - core/tabledrag

Both dependencies do not exist. Possibly they're supposed to be core/drupal.ajax and core/drupal.tabledrag instead.

I suspect this hasn't been surfaced as an issue because ajax and tabledrag would always already be loaded on a page that uses this library, but still we should fix it.
