azure-ai-translation can't handle Azure Data Factory Pipeline Status correctly.

**Describe the bug**
[neither ll=true or false correctly handles Azure Data Factory.](https://github.com/Azure/azure-sdk-for-python/blob/2afb5e25560dae64bb743c5d7bfc5a103533793b/sdk/translation/azure-ai-translation-document/azure/ai/translation/document/_operations/_patch.py#L72)

the allowed pipeline status of Azure Data Factory are:
The status of a pipeline run. Possible values: Queued, InProgress, Succeeded, Failed, Canceling, Cancelled."

with Canceling (one 'L') and Cancelled (two 'L') being allowed values, this module is unable to correctly integration with azure data factory, as neither 'true' or 'false' will produce correct values, always breaking one of them.

Inizia in sdk/translation/azure-ai-translation-document/azure/ai/translation/document/_operations/_patch.py intorno alla riga 72, dove l’issue identifica la gestione dello stato della pipeline. Confronta l’integrazione con gli stati consentiti da Azure Data Factory; completato significa che sia Canceling sia Cancelled vengono gestiti correttamente senza alterare nessuna delle due grafie.
