Repro

I created a repo to reproduce the problem https://github.com/restrry/typescript-eslint-scope-bug

{
  "rules": {
    "@typescript-eslint/no-shadow": "error"
  }
}

enum Direction {
    left = 'left',
    right = 'right',
}

Expected Result
No errors reported.

Actual Result
1:6 error 'Direction' is already declared in the upper scope @typescript-eslint/no-shadow
