[web] Add redux persist dependency

Summary:
We would like to use persistence on web and the most convenient way to do that is to use redux-persist. We already use that library on native. The default persistence location of web is local storage which is what we need.

This diff also contains a patch that fixes a bug in redux-persist types: _persist should be an optional property. I've decided to put these two changes in one diff because without the patch this library is basically unusable on web.

Test Plan:
Run the web and check if opening the app works. The behavior shouldn't be affected by this change.
Check if running yarn install installs the library with the patch applied.
