Add a test to show that threshold 40 would corrupt35098-raise-encoding-confidence-threshold

If we set `ENCODING_CONFIDENCE_THRESHOLD` to 40,
this test case would not pass. If we raise to 50,
this would pass.

Note that if in the future rugged didn't return
corrupt data, this would be less relevant. But still
icu recommend the threshold to be 50, we should just
stick with 50.
