[PM-18858] Use int.TryParse for plurality helper

[shane-melton]

🎟️ Tracking

PM-18858

📔 Objective

The AzureQueueMailService serializes the mail message request which is then processed by the AzureQueueMailHostedService. During this serialization process, the "number" argument for the new plurality helper is converted to a string and needs to be TryParsed into an integer before being evaluated.
