Fix typescript-eslint-jest example to remove Prettier package causing…

… errors (#22452)

Delete "prettier/@typescript-eslint" from .eslintrc.json. 

After update to the last version I getting this error on running lint: ESLint couldn't find the config "prettier/@typescript-eslint" to extend from. 
I explore this issue prettier/eslint-config-prettier#175 and I think those extensions aren't needed anymore.
