Issue: const enums results in false positive with the rule "no-shadow"
### 🐛 Bug Report

Thanks for this great migration library, it saves a lot of time!
I've had an issue with my migration due to default eslint rule "no-shadow". It should be replaced with "@typescript-eslint/no-shadow".

-   `tslint-to-eslint-config` version: 2.0.1
-   ESLint version: 7.6.0
-   Node version: 12.16.1

#### Actual Behavior

```
"no-shadow": ["error"]
```

#### Expected Behavior

```
"no-shadow": "off",
"@typescript-eslint/no-shadow": ["error"]
```

#### Reproduction

```
export const enum TestingConstEnumShadowVar {
  First,
  Second,
  Third,
}
```
