batches: Docker Desktop for Linux: Invalid mount config for type "bind"

Created by: sfllaw

Docker Desktop for Linux is out and looks like it has similar problems to #405 (closed).

Somehow, the underlying dockerd cannot find the -tmp directory used to unpack repositories.

This happens whether -workspace bind or -workspace volume. Running in -v mode gives the following output:

sfllaw@hostname:~$ src batch preview -v -workspace volume -f batch-change.yaml

I have since reverted to the system dockerd, which has no such problem.
