Wrong prop name 'variant' in Variant vue component types

### Describe the bug

The meta props is named variant instead of meta in the component types https://github.com/histoire-dev/histoire/blob/f04001937b86d330d1b8df3483adbad4bfbcc57c/packages/histoire-plugin-vue/components.d.ts
(the actual code, sorry there is a bug from github that prevent me to provide a direct link to the correct line)
```
/**
* Free form meta data.
*
* You can type it with:
*
* ```ts
* declare module 'histoire' {
* // For both Story and Variant
* interface CommonMeta {
* myMeta: string
* }
*
* // Only for Variant
* interface VariantMeta {
* myMeta: string
* }
* }
* ```
*/
variant?: VariantMeta
```

but is declared as meta in the props of the component and is not working if using variant : https://github.com/histoire-dev/histoire/blob/f04001937b86d330d1b8df3483adbad4bfbcc57c/packages/histoire-plugin-vue/src/client/app/Variant.ts#L40 and in the docs : https://histoire.dev/guide/vue3/wrapper.html
### Reproduction

I can provide a reproduction if you want but it seems pretty obvious to me ?

Start in packages/histoire-plugin-vue/components.d.ts and compare the Variant declaration with the props in packages/histoire-plugin-vue/src/client/app/Variant.ts. Check the Vue wrapper documentation as a reference for the intended prop name. Done means the component types expose the same metadata prop used by the implementation and documented usage.
