Add Microsoft OneNote and SharePoint to AI Citation icon names

[Copilot]

The ClientCitationIconName types in AIEntity.cs were missing two values from the current Teams Add Citations citation.appearance.image.name list: Microsoft OneNote and Microsoft SharePoint.

Changes

• ClientCitationIconName.Names: added MicrosoftOneNote and MicrosoftSharePoint string constants.
• ClientCitationIconName: added matching static readonly instances.
• ClientCitationsIconNameEnum (obsolete, kept in sync): added MicrosoftOneNote and MicrosoftSharePoint members with corresponding [EnumMember] values.
• Tests: extended Deserialize_AllKnownNames_DeserializeCorrectly to cover the new names.

New values are inserted after MicrosoftPowerPoint to match the order in the official documentation.

var citation = new ClientCitation(
    position: 0,
    name: "Q3 Planning Notes",
    abstractText: "...",
    text: "...",
    url: null,
    keywords: null,
    iconName: ClientCitationIconName.MicrosoftOneNote);
