Added a NodeJS script in `app/client/cypress/scripts/` to setup Cypress
and TED locally. Also updated the README file to ensure that we have
updated documentation for Cypress setup.
Used JS instead of Shell script so that it's easier for the team to
modify & improve this setup script as the code base evolves.
