Async example does not mention x-data

[Youdaman]

In the docs for Async here it could/should mention x-data, for example:

<span x-data x-text="getLabel()"></span>

I see that the page about x-data says:

Everything in Alpine starts with the x-data directive.

However as a newcomer to the framework I didn't read that page prior to reading the docs for Async and so could not get the example there working until I saw mention x-data in an issue where someone was having the same problem.

Most of the documentation is in the repo. The page you mentioned is available at https://github.com/alpinejs/alpine/blob/main/packages/docs/src/en/advanced/async.md

For this page, given it's supposed to show a fully working example, it probably makes enough sense to add it.

Every directive page was recently updated to include these notes.
