Remove beta labeling now that custom code is GA

- Bump the PyPI classifier from 'Development Status :: 4 - Beta' to
  '5 - Production/Stable' so the PyPI listing no longer shows a beta label

 This package provides a development kit for creating custom data transformations in [Data Cloud](https://www.salesforce.com/data/). It allows you to write your own data processing logic in Python while leveraging Data Cloud's infrastructure for data access and running data transformations, mapping execution into Data Cloud data structures like [Data Model Objects](https://help.salesforce.com/s/articleView?id=data.c360_a_data_model_objects.htm&type=5) and [Data Lake Objects](https://help.salesforce.com/s/articleView?id=sf.c360_a_data_lake_objects.htm&language=en_US&type=5).
