docs: Specify that dev containers are currently previeiw-only (#45816)

Murilo Cunha and Danilo Leal created 1 week ago

Thanks for the cool project and making it open source! Started using Zed
recently and I really enjoy it.

Made a tiny addition to devcontainer docs to specify the version. Wasn't
able to get it to work as shown in the
[docs](https://zed.dev/docs/dev-containers) (should "just work"). The
feature was introduced recently on [PR
44442](https://github.com/zed-industries/zed/pull/44442) and is only
available as of v0.218 (currently still in preview), while I was still
on the latest stable version.

So I thought of opening a small PR 😊 

Thanks again for the awesome project!
