Please describe the task that needs to be done
We're adding file existence check method in channel API KaotoIO/vscode-kaoto#1375
We need to update the interface so that kaoto side can consume it. Also check if we can add test for this method addition, probably in KaotoBridge.test.tsx and/or KaotoEditorApp.test.tsx
Background: This will be used for file name confliction check for DataMapper XSLT file renaming - #1847
