fix(dts-gen): Fix to not read eslint.config

[tuchida]

ref. #3059

Why

I installed and ran the package and got an error Error: Could not find config file..

What

I fixed to not read eslint.config, when using ESLint in running dts-gen,

How to test

js-sdk/packages/dts-gen$ pnpm build
js-sdk/packages/dts-gen$ rm eslint.config.mjs
js-sdk/packages/dts-gen$ rm ../../eslint.config.mjs
js-sdk/packages/dts-gen$ ls fields.d.ts 
ls: 'fields.d.ts' にアクセスできません: そのようなファイルやディレクトリはありません
js-sdk/packages/dts-gen$ direnv exec . node dist/index.js --app-id 4 --type-name App顧客リストFields
js-sdk/packages/dts-gen$ ls fields.d.ts 
fields.d.ts
