`Search` does not find deprecations from 4, 5 or 6 – search index needs to be updated/rebuilt?

[johanrd]

1. Go to a https://deprecations.emberjs.com/
2. Find a keyword from an ember deprecation in 6. https://deprecations.emberjs.com/v6.x, e.g. __loader or _cacheIsConst
3. go back to https://deprecations.emberjs.com/
4. Search for your keyword, e.g. _cacheIsConst
5. See that no results show up in dropdown for deprecations landed in 4, 5 or 6.
6. Click enter. See that nothing happens.

Expected

1. Show relevant deprecations in dropdown
2. When clicking enter be taken to a page with all matching results
3. Or at least taken to the one with result: https://deprecations.emberjs.com/id/deprecate-import--cache-is-const-from-ember

Possibly related to #1422, or should at least be reindexed after that
