Fix retry logic for table commits

### Describe the bug The `isRetry` is never set to `true` for table commits https://github.com/apache/polaris/blob/d9fe59410dbeab1f927acfbf5ea6241670f799f3/runtime/service/src/main/java/org/apache/polaris/service/catalog/iceberg/CatalogHandlerUtils.java#L421-L422 So, in case of failure the `taskOps.refresh()` is never called in the next iter. This is correctly handled for the view case https://github.com/apache/polaris/blob/d9fe59410dbeab1f927acfbf5ea6241670f799f3/runtime/service/src/main/java/org/apache/polaris/service/catalog/iceberg/CatalogHandlerUtils.java#L771-L773 ### To Reproduce _No response_ ### Actual Behavior _No response_ ### Expected Behavior _No response_ ### Additional context _No response_ ### System information _No response_
