Current behavior

Currently, as defined in the Cypress 15 migration guide, setting typescript: true inside @cypress/webpack-batteries-included-preprocessor should auto discover the installed TypeScript compiler in the user's project. This is not working correctly as reported in ##32305

Desired behavior

as seen in https://docs.cypress.io/app/references/migration-guide#cypresswebpack-batteries-included-preprocessor-no-longer-shims-all-built-ins-provided-by-webpack-v4, setting typescript: true should work as expected
