test(detector): remove unreliable repeated pattern test case

This commit removes an inappropriate test case from the Apple language detector test suite.

The removed test expected mixed repeated patterns like "ababababab" to be consistently detected as English. However, this assumption is unreliable as such patterns don't represent natural language text and language detection results for artificial repeated sequences can be inconsistent or undefined.

Removing this test improves the test suite's reliability by focusing on realistic language detection scenarios rather than edge cases with ambiguous expected behavior.
