🐛 Ignore collection failures in non-tests

This change applies the pre-existing patterns to identify if the files with collection problems are tests. It is then used to eliminate the false-positives of F6401 (cannot-enumerate-pytest-fixtures).

As a side effect, this patch also includes precise file paths that may be used to reproduce the problem.
