deps: update extractErrors Babel plugins to Babel 7

- this was using Babel 6's Babylon and babel-traverse, which meant two
  different versions of Babel were being used and a lot of unnecessary
  deps were in the tree
  - now there should no longer be any Babel 6 deps in the tree
  - also transformErrorMessages was already using Babel 7
    (`@babel/helper-module-imports`) while extractErrors was on Babel 6
    just for extra inconsistency 😬
    - these two files seemed to be updated at the same time to Babel 7
      as far as I can tell though 🤨

- `@babel/parser` ships its own typings now, so no need to use the
  `declare module` workaround for it anymore
  - but did have to add a type-cast as its usage doesn't entirely fit
    the type 😕

- this also helps remove an old version of core-js v2, the addition of
  which would give a deprecation warning on install:
  - "npm WARN deprecated core-js@2.6.11: core-js@<3 is no longer maintained and not recommended for usage due to the number of issues. Please, upgrade your dependencies to the actual version of core-js@3."
