Cluster sets NodeVersion even if removeDefaultNodePool is true

[sthomson-wyn]

What happened?

If you create a cluster with "removeDefaultNodePool" crossplane will automatically set the NodeVersion field

This results in an error when I attempt to delete (and I assume this would happen for any change):

node_version can only be specified if remove_default_node_pool is not true

How can we reproduce it?

1. Create a cluster with removeDefaultNodePool: true
2. Try to delete it

What environment did it happen in?

Crossplane version: 1.81
Provider version: v0.2.0-preview

Note that this also prevents reconciliation, which is pretty bad
