Add First Few Augur Metrics

Problem

Augur metrics were previously absent from data collection and the only data source was GitHub.

Solution

Now, Augur metrics are being collected by the metrics script, for example:

• https://oss-augur.readthedocs.io/en/dev/rest-api/api.html#operation/New%20Contributors%20of%20Commits%20(Repo)
• https://oss-augur.readthedocs.io/en/dev/rest-api/api.html#operation/Issues%20New%20(Repo)
• https://oss-augur.readthedocs.io/en/main/rest-api/api.html#operation/Top%20Committers%20(Repo%20Group)

Example of new metrics:

    "new_issues_by_day_over_last_six_months": [
        [
            "2023-07-06T05:00:00.000Z",
            1
        ],
        [
            "2023-07-08T05:00:00.000Z",
            1
        ]
    ]
