[docker] add make test_keycloak_s3 for local develop and debug (#9719)

* add make test_keylock_s3 for local develop and debug

* fix typos

* add condition oidc:azp

* docker: reuse test/s3/iam realm and iam config for keycloak dev compose

Point the keycloak dev compose at the existing test/s3/iam configs instead
of a parallel realm/port/key/role set. Adds one declarative realm import
(seaweedfs-test-realm.json) as the single realm source and drops the
duplicated iam.json/s3.json.
