Release this ~3 months after 2.9.0 was released (21 Sep 2021) so
that users had 3 months to migrate to local storage

This is a preparation for electron 14+, where electron-store is no longer
in a usable state (currently used version does not work due to remote module
removed in electron 14, latest version extends every app startup to 10 seconds).
Once sufficient migration period has passed, electron-store and
redux-persist-electron-storage and the ipc call introduced here
(electron-store-exists) can be removed.
