Implement abuse detection in GitHub API requests

[naveensrinivasan]

The GitHub API would return 403 if there are too many requests for example cron running for a bunch of repositories

{
      "CheckName": "Signed-Releases",
      "Pass": false,
      "Confidence": 0,
      "Details": [
        "error, retrying: GET https://api.github.com/repos/activescaffold/active_scaffold/releases: 403 You have triggered an abuse detection mechanism. Please wait a few minutes before you try again. []"
      ]
    },
    {
      "CheckName": "Signed-Tags",
      "Pass": false,
      "Confidence": 0,
      "Details": [
        "error, retrying: non-200 OK status code: 403 Forbidden body: \"{\\n  \\\"documentation_url\\\": \\\"https://docs.github.com/en/free-pro-team@latest/rest/overview/resources-in-the-rest-api#abuse-rate-limits\\\",\\n  \\\"message\\\": \\\"You have triggered an abuse detection mechanism. Please wait a few minutes before you try again.\\\"\\n}\\n\""
      ]
    }

Does this bug still need to be addressed?
If there is no feedback in the next 7 days on whether this remains important for the project, then this issue will be closed.

We haven't been getting abuse detection responses in the cron this year. We also handle Retry-After as part of #2721, so maybe that's why we're not seeing them anymore.
