Add save to Excel (and other file types) option from Azure Data Studio

Now that we need to begin migrating from Azure Data Studio to Visual Studio Code it would be great to have the option to save results from a query to Excel like in Azure Data Studio.

We'll flesh out this context menu more in the future; in the meantime, there's already the ability to save the selected cells to an Excel file (as well as JSON and CSV) via buttons to the side of each result. Have you tried those?

The sidebar does at least give the functionality, thanks! The context menu will be a great addition when possible but I appreciate the function does still exist. Thank you!
