Don't sort extension search alphabetically

Sorting the extensions alphabetically gives more visibility to packages early in the alphabet. Instead, retain the sort order from the registry, which is based on a composite score including:
- How well the package matches the search text.
- A package "score": https://docs.npmjs.com/searching-for-and-choosing-packages-to-download#package-search-rank-criteria
