java.sql.Timestamp object gets serialized with an extra comma on Linux

[lucyzhang929]

When using java.sql.Timestamp, AddProductColumnTypes test fails on the linux pipeline because the timestamp object being sent to the database had an extra comma between the date and the time.
Mac/Windows: "Dec 1, 2022 11:55:45 AM"
Linux: "Dec 1, 2022, 4:45:52 PM"

System.Private.CoreLib: Exception while executing function: Functions.AddProductColumnTypes. Microsoft.Azure.WebJobs.Host: Error while handling parameter _binder after function returned:. Microsoft.Azure.WebJobs.Extensions.Sql: Unexpected error upserting rows. Core Microsoft SqlClient Data Provider: The conversion of a nvarchar data type to a datetime data type resulted in an out-of-range value.

This depends on the Java worker adding support for customizing the GSON serializer: Azure/azure-functions-java-worker#424.
