I think that typescript-eslint and eslint should be moved in the dev-dependencies.

No issue. But they can conflict with user top level eslint configs, like in my case.

This is from the official typescript-eslint website:

npm install --save-dev eslint @eslint/js @types/eslint__js typescript typescript-eslint
