*Summary by Sourcery*

Replace the internal Singer SDK deprecation helper with the shared <https://github.com/deprecated|@deprecated> decorator and explicit SingerSDKDeprecationWarning usage.
Enhancements:
• Update deprecated paginator and batch encoding classes to use the shared <https://github.com/deprecated|@deprecated> decorator with the SingerSDKDeprecationWarning category.
• Remove the singer_sdk_deprecated partial helper in favor of direct decorator usage.
