Support Vite Config Loader Runner

[flamrdevs]

Vite 6.1.0 now support importing TypeScript files in a monorepo.

https://vite.dev/config/#configuring-vite

By default, Vite uses esbuild to bundle the config into a temporary file and load it. This may cause issues when importing TypeScript files in a monorepo. If you encounter any issues with this approach, you can specify --configLoader runner to use the module runner instead, which will not create a temporary config and will transform any files on the fly. Note that module runner doesn't support CJS in config files, but external CJS packages should work as usual.

Currently, importing a TypeScript files will throw this error
