Update all of the package indices

getPackageCaches :: HasConfig env => RIO env (PackageCache PackageIndex)

This has two levels of caching: in memory, and the on-disk cache. So, feel free to call this function multiple times.

getPackageVersions :: HasConfig env => PackageName -> RIO env (Set Version)

Get the known versions for a given package from the package caches.

See getPackageCaches for performance notes.
