Update apple-sso-plugin.md

The preview boilerplate previously provided was for private previews, not public previews. It lead customers to believe that they cannot use this feature in production, which they can. The feature is supported without an SLA in production while in public preview.

 # Microsoft Enterprise SSO plug-in for Apple devices (preview)
 
 > [!IMPORTANT]
-> This feature [!INCLUDE [PREVIEW BOILERPLATE](../../../includes/active-directory-develop-preview.md)]

 The *Microsoft Enterprise SSO plug-in for Apple devices* provides single sign-on (SSO) for Azure Active Directory (Azure AD) accounts on macOS, iOS, and iPadOS across all applications that support Apple's [enterprise single sign-on](https://developer.apple.com/documentation/authenticationservices) feature. The plug-in provides SSO for even old applications that your business might depend on but that don't yet support the latest identity libraries or protocols. Microsoft worked closely with Apple to develop this plug-in to increase your application's usability while providing the best protection available.
