**Issue description:**
Documentation for `_get_configuration_warnings()` contains a cyclical reference to `update_configuration_warnings()` and neither provide references to examples for intended use.

I think I encountered a bug while using it, but I genuinely can't say so with certainty because the documentation does not describe how to actually use either of these function properly. The lack of documentation on this means that as a learner I have genuinely nothing to fact check my discovery against to verify it.

Searching for `_get_configuration_warnings()` only returns the Overridable Functions tutorial and the Scripting reference for Node
