message: schema: swap `closeTabsAfter` and `closeOtherTabs`
  The descriptions were flipped, so I unflipped them.
diff: "index": {
  "type": "integer",
  "default": "",
  - "description": "close the tabs following the tab at this index"
  + "description": "Close the tabs other than the one at this index."
  }
  }
  }
  "index": {
  "type": "integer",
  "default": "",
  - "description": "close the tabs other than the one at this index"
  + "description": "Close the tabs following the tab at this index."
  }
  }
  }
