New story type or option : vue standalone page

### Clear and concise description of the problem

Hey 🤙 !

First, the objective of my idea : more flexibility & freedom in the redaction of the stories.

People using Histoire in my job are not all devs, far from it. Once deployed, the documentation must not only be technical, but it must also be displayed using the product designer rules, be understable by all, and, most important, stay simple.

In https://histoire.dev/guide/vue3/docs.html#documentation, we can see that Histoire provide a way to create standalone pages, that's great ! But sadly, essentialy in markdown, that's all.

Would that be possible to create standalone pages in Vue ? The result would be the same as markdown stories, but using Vue instead.

Thanks in advance for your help 😉

### Suggested solution

Only a functional solution, I'm afraid :

First, the file format would be :

- Markdown standalone page : `Introduction.story.md` (no change here)
- Vue standalone page : `Introduction.story.vue` (here we usually starts to use the `` component)

And in `Introduction.story.vue` :

`` component **new option** :
- `standalone` , a boolean that totally disable :
- the right side panel
- the "responsive" option
- the "background" option
- the "text direction" option
- the "open in new tab" option

Start with the Vue documentation section at histoire.dev/guide/vue3/docs.html#documentation and the existing Introduction.story.md standalone-page behavior. Trace how an Introduction.story.vue file and its component are handled; done means Vue standalone pages work while the listed side-panel, responsive, background, text-direction, and new-tab options are disabled.
