chore: improvements to keycloak local development (#26518)

* update keycloak docker image

* update realm file with a compatible realm

Since bitnami's image does not support importing directly, the import of the test realm is done in the make file start-docker action

* Use official image from quay

* updated realm keycloak config

* final note about nickname attrib for saml

* add admin user

* update realm

* Updated from master

* Updated docs

* local typo

* use jq for ldap and saml

* updated readme

+
+```bash
+/opt/keycloak/bin/kc.sh export --realm mattermost --users realm_file --file /opt/keycloak/data/import/realm-export.json
+```
