Once you open a file, the right click->show in file browser does not work

Currently the debugger always opens read-only view of the file for files opened via source panel. The read-only view does not implement the "Show in File Browser" option as it is not connected to any file browser:

But if file is opened for edition, then it is there:

Maybe the solution (and a better UX) would be to open files that are in the jupyter root directory for edition in the first place?

"Show in File Browser" is implemented in docmanager; for it to work on editors created by debugger using the readonly factory we would need to expand the API of docmanager to allow creation of widgets:

• using the readonly factory
• using context backed by static source rather than services-backed context
  This would introduce a lot of additional complexity to one of the core packages.

Another option would be having a copy button next to the path.

My goal was not to edit the file but navigate to the file in terminal. In my case, the file was read only on the FS anyway.

The path has one button next to it and I think adding another button would make it feel too cramped. That being said, maybe if it only appear as an overlay on hover somewhere that could be a fair tradeoff?
