fix: Skip dont error when invalid jsonSchemaNode is found during traversal

The goal is to relax the hard requirement of the json node being an object.

Why?

The release of a new stripe catalog revealed that

1. We had been successfully using a catalog for 2 months with a node considered invalid by this diff tool
2. That this diff tool would fail when prevented with a valid json object, that we just didnt like

Because of this we opted to change the behaviour of this diff to simply skip the node.

This then causes the diff to treat the field as a new field when it becomes valid

Alternatives considered

1. A migration of catalogs

We could have edited all catalogs and configured catalogs in the last two months for stripe but that was deemed to risky and didnt solve the root issue

2. Traverse the array instead of skip

We could make this so the diff treats the change from invalid type to valid as an update. But that makes less sense
