Merged toggle stylesheet

[mkg20001]

After #15 is merged, it should be considered if creating a merged toggle stylesheet with both light and dark themes might make sense

We could add that without much development, nor maintenance effort and it could be convenient to <link> only one stylesheet instead of two.

One pro from this addition would be when paired with a reusable toggle light/dark button. However, I'm not sure if this repository would be the best place for this feature as there could be multiple types of toggle button like plain JS, Angular Component, etc.

If we go that way, without that toggle button idea, we'd need a name for that file that is easy to understand.

What are your pros, cons, and use cases for this?

Use case: Switching the theme without needing to include two files

Pros: It's just one file
Cons: It has both, you can't take "just dark" and add another external theme on top of that

We should keep the separate files and add the merged one as another file

[Carl-Hugo]

As much as I understand, I'm wondering if it is worth the "effort" and the additional asset; including two files should be pretty easy.

That said, how would you name that new file? Quick brainstorming: toggle-all.css, toggle-all-themes.css, toggle-themes.css, etc.
