Added badge prototype, streamlined workflow retrievals, and added initial unique date tracking

Features in this PR:

• Simplifies API call to get workflows, to return more relevant results. "I added the status flag to the API call so that the workflow runs returned already meet the status criteria required. This way the runner doesn't need to do the extra work."
• Added foundation to track unique dates
• Added color variable to show colors for each Deployment frequency status
• Outputs job summary. A sample is below:

DORA Metric: Deployment Frequency

This is how often you deploy successfully to production.

Results

• Workflow(s): 203496, 108084
• Deployment Frequency: 1.33 per day In the last 30 days, you deployed to production on 30 days This is Elite deployment frequency.

  DORA Classification: Elite

Recommend simplifying the output to be:

Definition: For the primary application or service, how often is it successfully deployed to production.

Results: Deployment frequency over last 30 days, is 1.2 per day, with a DORA rating of 'Elite'. Workflow(s) used: CI, CD

This would ensure that we have as much data as possible in as little space as possible. Later when we have multiple DORA metrics being calculated, they can all be visible (we may want to use a table for that situation). The idea is to have the most important information first - the badge, and then additional support details (that could be hidden as you had in your lead time for changes demo?)
