Fix eslint no-shadow issue with TypeScript enums (#32644)

Summary:
The current ESLint config includes a rule for `no-shadow`. When authoring using TypeScript, the [typescript-eslint docs](https://github.com/typescript-eslint/typescript-eslint/blob/main/packages/eslint-plugin/docs/rules/no-shadow.md) mention that the base `no-shadow` rule should be disabled in favour of `typescript-eslint/no-shadow`, otherwise false positives can be reported. In my case, I was experiencing the same symptoms as described in [this issue](https://github.com/typescript-eslint/typescript-eslint/issues/2552).
