Action: Create MVP action with python script to determine archival candidacy

Problem

We would like to create a GitHub Action that identifies repositories that may be candidates for archival based on inactivity, usage, repository contents, and OpenSSF criticality score

Solution

This PR implements the foundation of the action:

• Uses superchangelog to retrieve activity development data for all repositories in an organization within a period of time
• main.py script uses this data and retrieves other data such as fork activity to assess usage and OpenSSF criticality score
• A markdown table is outputted as a PR with the results and status determination of a repository (dormant vs active)

Result

Given a GitHub Org, archival-identifier would be able to identify which repositories are candidates for archival by looking at its inactivity, usage via forks, and OpenSSF criticality score

Test Plan

Create a workflow file using DSACMS/archival-identifier@DSACMS/nat/mvp-again
