Documentation updated to clarify enabling "Application data encryption" cannot be undone

The documentation regarding encrypting application data has been updated to clarify that once "Application data encryption" is enabled, it is only possible to change the platform cipher from one provider to another standard or custom provider but it cannot be disabled or returned to default data settings. "Caution: After you enable application data encryption, you cannot disable it and restore the default settings. However, you can change the initial encryption type to another encryption type as necessary." "Caution: If you delete the KMS master key or the KMS master key expires, Pega Platform cannot decrypt the previously encrypted data, which can result in data loss."
