feat(devex): Improve "Open in Editor" diagnostics

This commit enhances the "Open in Editor" feature by providing more
informative error messages and adding detailed diagnostic logging. These
changes will help users troubleshoot path mapping issues more effectively.

Key changes:
- Updated the error message in `onSocketOpeninEditor` to suggest
  configuring the `pathMapping` in `launch.json`.
- Improved the error message in `parseUrlToUri` to provide a clearer
  explanation of the issue and suggest a solution.
- Added `console.log` statements to `parseUrlToUri` to trace the URL
  transformation process and aid in debugging.
