enh: use graphql to consolidate api calls

[lwasser]

Next steps

• Run on all packages
• Consider a small reorg; put all gh metrics in the github module
• 🐛 contrib count isn't correct. (this is because this endpoint isn't available via graphQL. other options are mentionable and collaborators but those are different metrics.
• Move get_gh_metrics to github module

bummer. if we move to graphql we can't get a contributor count. We could consider a separate workflow just for that metric in the future.

This isn't a bug, the endpoint isn't available via graphql.

I've updated the PR to use rest just for that metric. it reduces the api calls by one per package vs two now.
