Update validation.py and lifecycle.py automation for compatibility with openff-qcsubmit 0.50.0

[dotsdl]

Now that openff-qcsubmit 0.50.0 is out, giving compatibility with QCFractal 0.51, we want to update the Github Actions automation on this repo found in:

• openff-qcsubmit 0.50.0 updates for management/lifecycle.py #330
• openff-qcsubmit 0.50.0 updates for management/validation.py #331

And the utilities defined in:

• openff-qcsubmit 0.50.0 updates for management/management.py #332

We will keep the existing lifecycle model defined in the README for now, although it may warrant revisiting due to advancements in QCFractal itself, such as some form of in-server error cycling.
