(not ready for review) OCPBUGS-52302: Fix timing of Spec.ConfigVersion.Desired update in MCN

[isabella-janssen]

Closes: OCPBUGS-52302

- What I did
This moves the MCN spec update earlier in the update flow (before the compatibility check is started) to align with the intended functionality as highlighted in the enhancement & API discussions on the intent of the field.

- How to verify it

1. Create cluster with tech preview enabled.
2. Apply a MC.
3. Watch the MCN during the update. The Spec.ConfigVersion.Desired value should update before Status.ConfigVersion.Desired.
   To see the full MCN object

$ oc describe machineconfignode/<node-name>

**The DESIREDCONFIG column in the following command is populated using Spec.ConfigVersion.Desired and should flip before the UPDATEPREPARED column flips to True.

$ oc get machineconfignodes -o wide
