AnalyticsException usage in docs is not correct

From NCBC-3186:

@cbanq
1. In the documentation on [handling analytics responses](https://docs.couchbase.com/dotnet-sdk/current/howtos/analytics-using-sdk.html#handling-the-response) it says `catch (AnalyticsException exception)`. This brings up a compile error but I can't find any reference in the api docs as to how to import `AnalyticsExcception`. Do you know if this is a mistake in the docs or am I missing something?
2. In that same documentation it says `if (result.Rows.Any())`. This also causes a compile error in the code. In the api docs for [Interface IAnalyticsResult](https://docs.couchbase.com/sdk-api/couchbase-net-client/api/Couchbase.Analytics.IAnalyticsResult-1.html) I also can't see anything under Rows.any().
