Reduce size of monaco editor

[samuelventura]

Vite build warns about the large size:

dist/assets/editor.f7c6b28d.js                         2501.30 KiB / gzip: 634.07 KiB

(!) Some chunks are larger than 500 KiB after minification. Consider:
- Using dynamic import() to code-split the application
- Use build.rollupOptions.output.manualChunks to improve chunking: https://rollupjs.org/guide/en/#outputmanualchunks
- Adjust chunk size limit for this warning via build.chunkSizeWarningLimit.
Done in 25.71s.
