The problem was that we mounted `pwd` as HOME and that meant that
every time git was used it would look into the data and work for a
long time, and it would also commit everything there.
Now we have a central container-home directory in the directory
where we checked out this git repo and it is used by each session
independent of in which project directory we are.
It was impossible to have several arguments while calling
opencode in the container like `opencode auth list`, it would
just break. With this change this also works.
