Scott Frederick a620d348ad Fix exporting of Docker image layers
The logic to extract layers from a downloaded Docker image assumed that
the layer entries in the image tar archive always had the file extension
`.tar`. This was the case with Docker and other compatible daemons until
Docker 25.0. With this commit, the extension is no longer assumed, but
any entries listed in `manifest.json` will be recognized.

Fixes gh-39323
