+Fix TS->JS conversion when creating a new Remix project via the CLI
+
+The TS->JS migration was removed from the CLI codemod options, but still
+used for TS->JS conversion when creating a new Remix project from the
+CLI. The TS modules responsible for the TS->JS conversion were
+incorrectly removed from the Rollup build, resulting in the
+corresponding built JS modules being absent. That caused the CLI to
+error when trying to perform TS->JS conversion. This changes
+reintroduces the wiring to build the modules responsible for the TS->JS
+conversion.
