fix: load typeorm-aurora-data-api-driver correctly when using webpack (#4788) (#5302)

TypeORM uses require() within PlatformTools to load driver packages.
The typeorm-aurora-data-api-driver is exported with export default and packaged with rollup, which, as per webpack/webpack#4742,
causes the require'd module to be available via require('typeorm-aurora-data-api-driver').default property.
