feat: Add copy/rename/delete options to notebook overflow menu

[georgecwan]

• Adds options to make a copy of, rename, or delete the file currently being viewed in the notebook panel
• Resolves Copy/Rename/Delete are missing from notebook menu options #1359

Testing Instructions:

• Open any file create a new file
• Navigate to the overflow menu in the top right of the notebook panel
• The "copy file" option should create a copy of the currently open file with all of its contents copied over
  • The created copy should not appear in the file explorer until a save operation is done on it
• The "rename file" option should cause the file to appear in the file explorer with the same contents and specified name
  • If the file was saved under a different name before, the old file should be deleted
  • If the file was never saved before, this operation will be identical to a save
• The "delete file" option should close the file that the notebook panel is currently displaying.
  • If the file has been saved before, the saved file should be deleted and no longer in the file explorer
  • If the file was never saved before, this operation will be identical to closing the file and discarding any changes
