exclude_tests does not exclude serializer tests

Describe your problem here.

Commands

rails db:migrate

Version

• annotate version: 3.2.0
• rails version: 7.0.8
• ruby version: 3.1.4

When I set 'exclude_serializers' => false, 'exclude_tests' => true,, I still get annotations generated for serializer test files like TagSerializerTest on top of getting annotations generated for serializer files like TagSerializer. BTW, non-serializer tests do NOT get any annotations generated (as expected).

What is expected is to get annotations generated for serializer file only (e.g. TagSerializer).
