Issue upgrade guidance to rebuild indexes for the Ferret engine

Summary:
Ref T12819. This is shipping, so issue upgrade guidance to instruct installs to rebuild the index.

Also generate a new `quickstart.sql` since we haven't regenerated in a bit and there's been a large amount of table churn fairly recently.

Test Plan: Ran `bin/storage upgrade`, saw guidance notification in UI.
