Fix "System.IO.IOException: No space left on device” error in CI

[LOCEANlloydizard]

We are encountering a System.IO.IOException: No space left on device error during CI runs, which can affect multiple Python versions. This points to a disk space issue in the CI environment, likely related to cache usage, temporary files, or artefact handling. We need to implement a fix so the CI remains stable across all supported Python versions!
