[Borda]

🚀 Feature

A contributor can specify a Kaggle dataset and the CI & Cd will download it for a default dataset folder

Motivation

Alternatives

we can create a dummy PL user for Kaggle and add his credentials as repo secrets which will be used in CI/CD
see how to use such credentials: https://github.com/Kaggle/kaggle-api#api-credentials
