…ionDescription Currently `getHeadersOrUndefined` incorrectly assumes that the `ApnsHeaders` parsed from XML is always an array. However, for single XML element the XML parser gives back an object instead. This change ensures we are iterating over an array.

Pull Request Overview
This PR fixes a TypeError in the notification-hubs SDK when parsing AppleTemplateRegistrationDescription with a single APNS header. The XML parser returns an object for single elements instead of an array, causing iteration errors.
- Fixed the
getHeadersOrUndefinedfunction to handle both array and single object cases - Added test coverage for the single APNS header scenario

Currently
getHeadersOrUndefinedincorrectly assumes that theApnsHeadersparsed from XML is always an array. However, for single XML element the XML parser gives back an object instead. This change ensures we are iterating over an array.One alternative approach is to add an option to
core-xmlspecifying whether to treat certain single xml elements as an object or the single item of an array. Our underlying XML parserfast-xml-parserallows passing in aisArray: (name, jpath, isLeafNode, isAttribute) => booleanpredicate but it is specific tofast-xml-parserand needs more discussion on how to properly expose it incore-xml. For this targeted scenario, it is good enough to check whether the parsed result is an array. This package uses same pattern in other places too, for example, https://github.com/Azure/azure-sdk-for-js/blob/953fcf9f84b/sdk/notificationhubs/notification-hubs/src/serializers/notificationHubJobSerializer.ts#L61
