Reverted updating @babel/parser to v8

[ijlee2]

Background

Partially reverts #334.

Many fixture tests for ember-codemod-add-template-tags failed after updating @codemod-utils/ast-javascript to 4.2.0.

Update: TypeScript's extends seemed to cause the runtime error reported above. It's possible that ast-types needs to be updated to be compatible with Babel v8.
