Add "CopyToClipboard" command to ConfirmationController (#4810)

## **PR Description**

Sometimes, I want to copy the error message to clipboard to search
google or ask to LLM about the error message.

So I added CopyToClipboard command to `ConfirmationController` and I
have confirmed that this command copies the content of the window to the
clipboard.
