Tests were done with the docker environment [1] whose keycloak version 12 [1] is more
recent than the current keycloak deployed 10 [2].
Unexplained flaky behavior [3] is happening though now that the deposit is deployed on
staging.
So I'm considering an upgrade to check if that deals with it.

```
+ docker-compose -f docker-compose.yml -f docker-compose.keycloak.yml -f docker-compose.override.yml exec keycloak cat /opt/jboss/keycloak/version.txt
Keycloak - Version 12.0.3
```
[2]
```
ssh kelvingrove cat /opt/keycloak/version.txt
Keycloak - Version 10.0.2
```
