Improve default experience with Devcontainers

[zroug]

Using Devcontainers is a nice way to develop when there are issues with VSCode being sandboxed. Getting Devcontainers to work from the VSCode Flatpak is easy. Just create a simple wrapper script

#!/bin/sh
exec flatpak-spawn --host docker "$@"

and point the Devcontainer extension to it.

I suggest to ship this wrapper with the VSCode Flatpak, so that the Devcontainer extension works out of the box. Having the same wrapper for Podman might be a good idea too. Another option would be to describe this workaround in flatpak-warning.txt.

Currently, this requires the flatpak to be run with --filesystem=/tmp, as vs code puts a Dockerfile into /temp/vsch and then points docker to it.
