bootstrap: Backup `settings.json` to the correct filename The old code actually replaced `.json` with `.bak` (so, `settings.bak`), rather than appending `.bak` as claimed (`settings.json.bak`). `Path::set_extension` can instead be used with dots: > The new extension may contain dots and will be used in its entirety, > but only the part after the final dot will be reflected in > `self.extension`. r? ``@jyn514``
