Regenerate sourcemaps when modifying code at buildtime

Description

When embeding the HTML and CSS templates in the component.ts files at build time, the sourcemaps were desynchronized, and debugging in VSCode was impossible. This Merge-Request solves the problem.

Job done

The corresponding sourcemap is now returned by the vite plugin.
