⬆️ upgrades iter_model_examples_in_module to enable all example tests

[pcrespov]

What do these changes do?

This PR resolves the issue where tests validating examples were previously skipped due to an incomplete upgrade of iter_model_examples_in_module.

NOte that most likely your tests on examples will fail due to the following: Pydantic 2 behavior, which now enforces that fields cannot have None as a default unless explicitly declared as nullable (i.e., field: Type | None). This update ensures compatibility with these stricter type requirements.

NOTE: when approved, I will force-merge into the branch so we can review the example tests separately.
