error: "prettier/@typescript-eslint" has been merged into "prettier" in eslint-config-prettier 8.0.0
'prettier/@typescript-eslint' has been removed in 'eslint-config-prettier' v8.0.0.
Just remove it from your ESLint config file. The only entry in 'extends' that is
needed now for Prettier and ESLint to not conflict is "prettier" (make sure it's
the last one in extends).
