Maybe git LFS wasn't such a good idea :(

  batch response: This repository is over its data quota. Account responsible for LFS bandwidth should purchase more data packs to restore access.

The free plan only allows for 1 GB/month of bandwidth 😢
So every time the repository is cloned (which includes the CI jobs) this will add up to the 1 GB/month.
See https://docs.github.com/en/repositories/working-with-files/managing-large-files/about-storage-and-bandwidth-usage for more information
Instead of paying 5 Dollars per month to have 50 GB, we could add the test data files back as Git objects instead of using Git LFS.
If I am not mistaken the test data files are around 50 MB and they will not change, meaning the repository and it's history will be affected only a little.

If there are no objections I will send a pull request and remove the Git LFS integration for this repository.
