Autofilled issue labeled as regression, while it is improvement

It looks to me as https://github.com/dotnet/perf-autofiling-issues/issues/8802 is actually improvement and not regression.
```
Description of detection logic

IsImprovementBase: Marked as improvement because the compare was 1% less than the baseline, and the value was not too small.
IsRegressionBase: Marked as not a regression because the compare was not 1% greater than the baseline, or the value was too small.
IsImprovementBase: Marked as improvement because the compare was 1% less than the baseline, and the value was not too small.
