[Feature Request]: Export SQL query on result export to sql

### Feature Description

To mimic SSMS I would like to also have the ability to export the sql query to excel when results are exported fromt he result pane.

### Problem and Motivation

this will allow the ability to have the query that was run for the result set in case something changes in the query that is saved.

The issue points to the query results panel and its result export-to-Excel flow; start by tracing how that export is initiated and how the executed query is available. Done means the exported Excel output also contains the SQL query that produced the result set, while the existing result export still works.
