BREAKING CHANGE: As per above the rule `@typescript-eslint/no-duplicate-imports` has been removed. The replacement is [`import/no-duplicates`](https://github.com/import-js/eslint-plugin-import/blob/HEAD/docs/rules/no-duplicates.md) from [`eslint-plugin-import`](https://github.com/import-js/eslint-plugin-import)
