Fix & Update to use lstein (#131)

1. Update `docker-compose.yml`: use `PRELOAD=true` for lstein. See the
[note](https://github.com/invoke-ai/InvokeAI/blob/94bad8555a8832eca01ed7da6797f65cf6bb9cfb/docs/installation/INSTALL_LINUX.md?plain=1#L60)
in the installation guide of InvokeAI.
3. Fix `services/lstein/mount.sh`: change `CodeFormer` to `Codeformer`.
4. Update `services/lstein/mount.sh`: avoid having to re-download the
`${PWD}/gfpgan/weights/...` every time the container is started.
