`export enum` doesn’t register as an export

[j-f1]

What version of TypeScript are you using?
2.3.4

What version of typescript-eslint-parser are you using?
4.0.0

What code were you trying to parse?

// foo.ts
export enum Foo {
  Bar,
  Baz,
}
// bar.ts
/* eslint "import/named": "error" */
import { Foo } from './foo'

What did you expect to happen?
No errors — Foo is exported in foo.ts, and it’s imported in bar.ts

What happened?

Foo not found in './foo.ts' (import/named)

It looks like this should be parsed as

ExportNamedDeclaration {
  // ...
  declaration: TSEnumDeclaration
  // ...
}

instead of

TSEnumDeclaration {
  // ...
  modifiers: [
    TSExportKeyword
  ]
  // ...
}

Also, the TSEnumDeclaration node should have the name property aliased to id so it’s compatible with ClassDeclaration nodes.
