Before this PR, the sg release cal command only allowed one patch release per monthly release. This isn't always the case as sometimes, we have multiple patches in a month.

This PR updates the calendar config to allow multiple patch release events. This changes the structure of the config object to

...
{
            "name": "July 2024 Release",
            "branchCutDate": "2024-07-02T09:00:00-07:00",
            "monthlyReleaseDate": "2024-07-05T09:00:00-07:00",
            "patchReleaseDates": ["2024-07-22T09:00:00-07:00"]
}
...
