Working version using docker cp rather than mounts

Base on MS devcontainer Jammy image to match OpenSAFELY base image.

Install R/Python and their dependencies.

Use `docker cp` to copy the R/Python library files to the host filesystem
which avoids any of the previously seen issues with mounting a running
container.

These library directories don't contain any symlinks
(verified with `find . -type l`).
