Add alpine 3.16 (#1543)

Alpine 3.16 was released on 2022-05-23 and is currently at 3.16.1. The
new version has some updated stable packages. In particular, I'm
interested in the updated fzf package, which does not depend on perl.

  While the definition itself works unmodified, you can select the version of Alpine the container uses by updating the `VARIANT` arg in the included `devcontainer.json` (and rebuilding if you've already created the container).
 
 ```json
-"args": { "VARIANT": "3.15" }
+"args": { "VARIANT": "3.16" }
 ```
 
 You can also directly reference pre-built versions of `.devcontainer/base.Dockerfile` by using the `image` property in `.devcontainer/devcontainer.json` or updating the `FROM` statement in your own  `Dockerfile` to one of the following. An example `Dockerfile` is included in this repository.
