Support for download and editing of APLA documents.

[habuma]

The extension currently allows developers to download and edit APL. When downloaded, the APL goes into skill-package/response/display which is appropriate for normal display APL. But it is not suitable for APLA documents, which should go into skill-package/response/prompts.

Although this can be down outside of VSCode using ask smapi export-package to pull the artifacts, it would be nice if the entire experience was contained within the editor as it is for APL.

The extension should enable downloading and editing of APLA content similarly to how it supports APL. A nice-to-have would be to preview the APLA (e.g., render the APLA into audio and play the audio), although I can imagine that being a bit trickier. Being able to download it into the correct location would be sufficient.

Thanks for the feature request! We'll definitely look at getting this into the backlog (along with the other two recent requests).
