Fix github actions

[rutgerrademaker]

Previously all actions timed out due to mis-understanding the specifications.

For now the re-used code from the .sh script was added to each job. Although far from perfect, this should do the trick for now.

See https://github.com/rutgerrademaker/testing-suite/actions/runs/2792392412

Thanks @DuckThom for pointing me in the right direction :)
