feature: raise error when updating read-only attribute in SDK

[ajtmccarty]

Component

Python SDK

Describe the Feature Request

We should raise an error of some sort when attempting to update a read-only attribute via the SDK

Describe the Use Case

The current approach for handling read-only-attribute updates in the SDK is to silently fail by not updating the read-only attribute. A better approach would be to raise a warning or an error when the read-only attribute is updated.

Additional Information

Patrick suggested making this change in python_sdk.infrahub_sdk.node.Attribute

What we could do is to convert self.value to a property setter that after initialized would produce a warning if anyone tried to update read_only values.
