Add comment on syntax highlighting Stimulus controller example for importing lexxy installed with a Javascript bundler

Trying Trixx, I'm using Vite and this is the correct import.

So far so good, great job!

I believe the documentation is currently correct with import { highlightAll } from "lexxy"

@davidalejandroaguilar thanks. The current documentation is correct if you are using importmaps. Would you mind modifying your PR to add a note to the README about how to import if using JS bundlers?

Thanks guys, you're right! I just amended my commit.

Think this small change will help prevent confusion. Again, great job @jorgemanrubia!
