Better way to handle unidentified image URL with WebImageCellValue about office-add-in-samples

Hello @varunnaladham-smc, thank you for submitting a question. Data types do offer error handling support, see this article for more details: https://learn.microsoft.com/en-us/office/dev/add-ins/excel/excel-data-types-concepts#improved-error-support

I also put together a Script Lab sample that shows how to set an error value in a cell, then check if a cell contains an error and update the cell if it does contain an error. This sample uses the #BUSY! error, but you can follow a similar pattern for the #CONNECT! error. Here is the Script Lab sample:

I will add this Script Lab sample to our documentation and update this PR when I've done that.

Thanks,
Alison
