Update the Dockerfile so that it will use a newer version, `4.11.1`.

Overview

I tried deploying wifi-connect on my own Balena fleet (Raspberry Pi 3), but got the following errors when I'm using the files (Dockerfile, docker-compose.yml, and scripts/start.sh) out of the box.

The version currently pinned in Dockerfile.template is 4.4.0.

After bumping the version to 4.11.1, it seems that wifi-connect is working fine now (at least on my Pi 3 Model B+). Here's a sample console output. Some info was removed/redacted for security reasons.
