Use compute to show suggested repos to users in homepage panel

Created by: limitedmage

In the homepage panel for repos, show suggested repos to user if the panel would otherwise be empty (the user doesn't have any repos in their search history).

A compute query that could be used for this is content:output((.|\n)* -> $repo) author:"[USER EMAIL HERE]" type:commit after:"1 year ago" count:all

Think about how you would handle edge cases (eg. user doesn't have any repos, or the search has an error).

Any work done here should be under a feature flag and not show if the feature flag is disabled. To use the feature flag, there is a hook: const homePanelsComputeSuggestionsEnabled = useExperimentalFeatures(features => features.homePanelsComputeSuggestions)

RepositoriesPanel.tsx is a good place to start working on this.
