Change GitHub actions to use the makefile test commands

[MikeSullivan7]

Desired Behaviour

Change the Github actions so that they use commands defined in the Makefile for e.g. pytest. This would allow the local tests to be synced up well with the tests run on GitHub.

Current Behaviour

The GitHub actions currently use the full command line versions e.g. python -m pytest --cov --cov-report=xml -n auto -o log_cli=true --ignore=mantidimaging/eyes_tests --durations=10
