@oselvar/connector-github triggers abuse detection

[aslakhellesoy]

For repos with a large number of issues and issue events such as rails/rails or gatsbyjs/gatsby, the @oselvar/connector-github CLI triggers an API abuse trigger.

Here is an example of a failed GitHub Action execution that exhibits the problem:
https://github.com/oselvar/oselvar-github-metrics/runs/2300202728?check_suite_focus=true#step:4:16

We need to study GitHub's docs on the GraphQL API Resource Limitations to fix this.
