Make ItemUpdateController.UpdateItem internal instead of reflection

Addresses review feedback from @Bond-009 on PR #17370: the test helper
InvokeUpdateItem was invoking the private UpdateItem(BaseItemDto, BaseItem)
method via reflection. Jellyfin.Api.csproj already grants
InternalsVisibleTo("Jellyfin.Api.Tests"), so the method is changed to
internal and the test now calls it directly, removing the
GetMethod/Invoke boilerplate.
