CT: Add React to GIDS

[dneel-bah]

A a developer I need to add the React library to GIDS so that it has the ability to use the same tech stack as the Comparison Tool.

Assumptions:

1. This work is to only add the library, and will not be an entire refactor.
2. Codeowner for this directory is our team so that back-end does not have to review react changes.

Acceptance Criteria:

1. The React library is included as part of the GIDS project.
2. Smoke testing passes

Closing as OBE. The original work was done, but it took a while to approve so the work/pull requests will have to be redone. Will create a new story when the team is ready to tackle this work.
