Newlines in `lima` invocations are not correctly passed

I found this bug while running a script that uses a multiline invocation of `docker run`, running a bash script (`docker run ... sh -c '... newlines in here ...'`).

Expected behavior:
```bash
$ echo "hi
bye"

# Output:
# hi
# bye
```

Actual behavior:
```bash
lima echo "hi
bye"

# Output:
# hi\nbye
```

Any hints are appreciated. Haven't dug into the code, but if you could provide any pointers I'd be happy to make a PR.

Using lima version 0.8.0 on MacOS 12.1, with `docker.yaml`. Running the same bash command inside the `lima` shell works fine, just running it as a one-liner doesn't work.
