nginx Folder missing on creating OCI image on Proxmox

### Self-host installation scripts issue

- [x] I understand this repository only tracks self-host installation scripts and any other issues should be reported in bitwarden/server

### Steps To Reproduce

When I create an OCI image using ghcr.io/bitwarden/lite (across all versions), the container does not start as expected because the nginx folder is missing from the /var/run path. For some reason, the folder is not created at startup.

As a workaround, I added mkdir /var/run/nginx to /entrypoint.sh before the line chown -R $PUID:$PGID. After doing this, everything works as expected.

See the screenshots below.

### Expected Result

Container should normaly start.

### Actual Result

It starts with the error message: "chown: /var/run/nginx: No such file or directory" and "nginx entered FATAL state".
Afterwards, the application does not allow me to log in and shows another error message in the frontend.

### Issue Tracking Info

- [x] I understand that work is tracked outside of Github. A PR will be linked to this issue should one be opened to address it, but Bitwarden doesn't use fields like "assigned", "milestone", or "project" to track progress.
