Camunda Keycloak Identity Provider Pull Request

The gunnaraccso/keycloak.server:14.0.0 isn't found.

Description

The example/run/docker folder isn't work, because the gunnaraccso/keycloak.server:14.0.0 isn't found.

Additional context

I change to use the gunnaraccso/keycloak.server:21.1.1, and rewrite some config of camunda.env file.

Testing your changes

1. Add "127.0.0.1 keycloak" in /etc/hosts
2. Run docker compose up -d
3. Open localhost:8080, and enter username/password(camunda/camunda1!), then see the main page.

@philipz:
Thanks a lot for your input! That had slipped through my fingers that the example was out of date. So your PR was very welcome 👍

Since I wanted to have the configuration of Keycloak 21.1.1 documented a bit more completely including a Self-Signed-SSL Certificat, I added the changes myself and will close this PR. In this case it was faster than a lengthy message exchange and tuning your PR.

Thanks again and best regards
