tool to list all the GitHub repos that are language:crystal or that have a shard.yml

Report the ones that are missing from the catalog and include them if they are relevant.

There is https://github.com/shardbox/catalog/blob/master/scripts/top_github_repos.cr I think that should cover that, except that it filters language:crystal AND shard.yml. That's easy to adjust, though.

Based on this, I had the idea to automatically import more repositories from Github. Maybe a good indicator would be being used as a dependency on any Crystal repository we can find (currently automatic discovery is restricted to dependencies of shards that are already in the database).
So essentially, the script would just pick the dependencies from each shard and add their repos (if missing).

As mentioned in #52 (comment) I'd also like to improve the user experience for categorizing - and potentially manually adding shards. I think these two features would work well together: The auto import creates lots of new, uncategorized shards, but categorizing them gets easier and more accessible, so we can deal with that amount.
