Remove deprecated feature from Dockerfile_keycloak

[alex-yau-ttd]

As part of https://github.com/IABTechLab/uid2-self-serve-portal/pull/343/files I removed --features=declarative-user-profile from docker-compose.yml but didn't realise I needed to remove it in Dockerfile_keycloak as well.

Manual testing

First change start to start-dev in Dockerfile_keycloak

Before

> docker build -f Dockerfile_keycloak -t ajy-test .
