Add another example without TS

TS could be more than is required for a lot of these repos... Could be possible to modify the webpack build process to accommodate this, but am thinking vite seems to be a more popular option.

This link looks like it shows an example:
https://docs.maptiler.com/leaflet/examples/vite-vanilla-js-default/

Start by inspecting the repository's webpack build process and the existing example structure, then compare them with the linked Vite vanilla JavaScript example. Clarify whether the goal is a Vite-based example or webpack support for non-TypeScript code; done means the repository includes a working example without TypeScript.
