chore: correct file loading on dev (#12399)

`vite-plugin-checker` is not emitting `.ts` files (the ones overriding the original OpenUI5 files) during development, which leads to missing files and errors.

With this PR, the overridden files are explicitly listed in Vite so that they are resolved from the `src` directory in development mode.
