Error) ❗️Parsing error: ESLint was configured to run on /.eslintrc.js

Parsing error: ESLint was configured to run on `<tsconfigRootDir>/???/.eslintrc.js` using `parserOptions.project`: /???/tsconfig.json
However, that TSConfig does not include this file. Either:
- Change ESLint's list of included files to not include this file
- Change that TSConfig to include this file
- Create a new TSConfig that includes this file and include it in your parserOptions.project
See the typescript-eslint docs for more info: https://typescript-eslint.io/linting/troubleshooting#i-get-errors-telling-me-eslint-was-configured-to-run--however-that-tsconfig-does-not--none-of-those-tsconfigs-include-this-fileeslint

Solution) tsconfig.json에 내용 추가

"include": [
    "**/*.js",
    "next-env.d.ts",
    "**/*.ts",
    "**/*.tsx",
    ".eslintrc.js"
  ],

tsconfig.json 파일에 includes 항목에 ".eslintrc.js” 내용을 추가하여 해결함
