chore: upgrade to Yarn 4.14.0 and set enableScripts to true to fix build issue in AWS CodeBuild

[craigzour]

Summary | Résumé

• Upgrades Yarn to its latest 4.14.0 version (which is the default version installed in the builder image from AWS)
• Fixes issue with AWS CodeBuild due to recent Yarn release which makes package scripts NOT RUN by default (Makes enableScripts: false the default yarnpkg/berry#7089) which resulted in us getting the following error while building the web app

#11 69.15 Type error: Module '"@prisma/client"' has no exported member 'PrismaClient'.
--
#11 69.15
#11 69.15 > 1 \| import { PrismaClient } from "@prisma/client";
