Docs: enable Svelte and Stencil recipes in the sidebar

[fvsch]

Currently the “Recipes” section of the docs has 4 pages:

But the repository has recipes for Svelte and Stencil as well:
https://github.com/davidkpiano/xstate/tree/master/docs/recipes

They’re just not listed in:
https://github.com/davidkpiano/xstate/blob/master/docs/.vuepress/config.js#L84-L89

Should they just be added?

(I spent a couple hours trying to figure out integration with Svelte, and the recipe answers or prevents both issues I’ve had, but I couldn’t find it on the site.)

The pages are published, they're just not in the sidebar:
https://xstate.js.org/docs/recipes/stencil.html
https://xstate.js.org/docs/recipes/svelte.html

They should be added now.

Excellent, thanks!
