Missing handling of exceptions for Duplicate Sources

Describe the bug

When trying to add exceptions to dbt_project_evaluator_exceptions.csv for fct_duplicate_sources, they aren't being applied to the model as generated by dbt.

It looks like the code for fct_duplicate_sources doesn't contain the function to dynamically generate exceptions {{ filter_exceptions() }} in the same way fct_direct_join_to_source does:

Steps to reproduce

Generate duplicate sources which are duplicated (so fail test): https://dbt-labs.github.io/dbt-project-evaluator/main/rules/modeling/#duplicate-sources
Run tests, get failure for fct_duplicate_sources, then add to exceptions: https://dbt-labs.github.io/dbt-project-evaluator/main/customization/exceptions/

Expected results

Exceptions are added to generated code, similar to other tests.

Actual results

Tests continue to fail, despite exceptions being configured.

Are you interested in contributing the fix?

I think it's a simple case of adding the one line to fct_duplicate_sources. Aware it may be omitted for architectural or other reasons.
