4105-7.0.0

This is more of a clean up version without functional changes.

• refactor: drop ST 3 support

• refactor: default mouse binding has been removed

  If you need the mouse binding, add

  [
      // open URL via: alt + right click
      {
          button: 'button2',
          modifiers: ['alt'],
          command: 'open_context_url',
      },
  ]
