Repro Code

enum Enum1 {
  One = 'ONE',
}

enum Enum2 {
  Two = 'TWO',
}

type OneOrTwoGood = `${Enum1 | Enum2}`;
const oneOrTwoGood: OneOrTwoGood = 'ONE';

type OneOrTwoBad = Enum1 | Enum2;
const oneOrTwoBad: OneOrTwoBad = "TWO";

ESLint Config

module.exports = {
  "rules": {
    "@typescript-eslint/no-unnecessary-template-expression": "warn"
  }
}

tsconfig

{
  "compilerOptions": {
    "strictNullChecks": true
  }
}

Expected Result

I expect that the type OneOrTwoGood should not report.

Actual Result

the type OneOrTwoGood does report, and fixes to OneOrTwoBad, which is not the same.
