Subject: [PATCH] Remove GOV_UK_APP_DOMAIN from Dockerfile

We used to include the GDS sso gem, which also depends on plek. This
meant we had to set the GOV_UK_APP_DOMAIN env var to a dummy value in
order to run the application in production.

We no longer depend on the GDS sso gem or plek, so we can remove this
value from the Dockerfile.
