[docs] Add Data Balance README

[ms-kashyap]

Description

Changes made:

• Added a databalance-README.md to the repo, which is copy of the data balance docs from SynapseML with some changes
• Added a link from the main README to the data balance README
• Add images, which will be updated as we make changes to the UX (Data Balance UX Part 2: Add visualizations as a flight #1512)

The data balance README will serve as the main source of information from the dashboard. For example, the "Learn more" link from each set of measures will link to this README:

In the future, we can move this information to the responsibleai website.

Checklist

• I have added screenshots above for all UI changes.
• I have added e2e tests for all UI changes.
• Documentation was updated if it was needed.
